Chapter 1: The Mandalorian - S1-E1
Plot hole: Nick Nolte's little guy is supposedly terribly helpful towards Mando, showing him "the only way" to reach the enemy encampment, which is by riding the weird fishy beast, but when Mando surveys the target and the robot reveals itself, you can see that there are only shallow hills around the base, a large clear path of land, nobody even is on lookout...and most importantly, in the following episode, Mando makes it back on foot anyway, no blurrgs - and evidently the baddies had no vehicles, making them even less of a threat to begin with. And for being so helpful and good natured, he did not tell him to park the ship by/at his place nor warned him about the Jawas.
Plot hole: It is a well-known fact that Mando is the one who got the bounty for the target, and the bounty has already been cashed in. Fobs are, as shown, specific for just one target and bounty hunters return them. Yet everyone hanging around at the cantina has still theirs. And again, the bounty was already cashed in, and surely the imperial guy does not have another bucket of incredibly rare and precious metal to give away.
Plot hole: Mando tells Cara that news will travel of what happened on the planet and it's unsafe to stay there. Then he says that he'll go and leave the kid to live there. He is a bounty hunter, a veteran at the profession. He can't have forgotten about fobs and how they work, and that the bounty is on the kid. Wherever Mando himself goes makes zero difference. (00:31:25)
Chapter 5: The Gunslinger - S1-E5
Plot hole: Something about the timing of the episode does not work. The two pursuers see in their first day of chase a dewback (animal mount). They storm Fennec's position when it gets dark. They quickly capture her, and then Mando wanders the desert to catch the dewback. It takes him the whole night to do so and get back to the encampment, which seems an absurdly long time considering he had it in his sight (and was even sending for it his partner who had no thermal vision). This also implies that Fennec was in the middle of the desert with no mean of transportation of her own.
Chapter 6: The Prisoner - S1-E6
Plot hole: When the distress signal is launched, approximately 20 minutes are left till the arrival of the New Republic fleet. From the control room the team arrives to the prisoner's cell with 15 minutes to spare. They lock Mando up, and next time they communicate with their getaway robot dude, it says there are only 10 minutes to go, meaning it took them an astonishingly long time to navigate the ship without being really much closer to the exit, having met no opposition. Then the episode turns into a slasher movie of sorts, and somehow Mando manages to find them separately, hunt them down and as it turns out, not simply disposing of them, but also drag their unconscious carcasses to the empty cell he escaped from. There's nothing coherent about this timeline.
Chapter 7: The Reckoning - S1-E7
Plot hole: Kuiil is shown salvaging the droid from the building's ruins. A campfire is still burning and the droid's remains are still smoking, but at the end of the mission he spent a couple days at least with Mando on the jawas' sidequest. The only time when he could have got the robot when the ruins were still smouldering would have been right after Mando left, but that implies he's been a huge jerk not giving him a ride, and lied to him when he acted surprised he was still alive - it's also impossible he could have had the droid on his property without Mando seeing it and freaking out. (00:09:50)
Chapter 7: The Reckoning - S1-E7
Plot hole: The boss of the boss murders Werner Herzog because he knows that the baby is not in the crib. Yet it takes Mando's message (somehow intercepted) for the troopers to start moving in pursuit. The heck were they waiting for? They have overwhelming forces in the area and a previous deal with Karga. (00:33:10)
Chapter 7: The Reckoning - S1-E7
Plot hole: The Client does not care if The Child lives or dies, in fact he sent out bounties for the baby to be delivered dead, without even offering the incentive. But as if it were an SNL spoof, he is slowed down by Greef Karga's comment about the baby being asleep. Pretty amazing to begin with that the crib, aka an object completely sealed that could contain anything from a bomb to some form of killer droid or a stash of weapons, is allowed in without the faintest inspection. Not to mention that he is loaded with tracking fobs for the baby. He should be alerted just by not hearing beeps from the devices.
Plot hole: The flamethrowing trooper enters, entirely on his own, walking slowly through the door, and neither Cara nor Greef, who are armed and not wounded, shoot at him, for no discernible reason other than giving the Child a little pyromancer moment. And of course, Gideon wants the baby ALIVE; burning the place to a crisp kinda goes against all of that, but he is the one who ordered that. (00:20:50)
Plot hole: Mando thinks that the other Mandalorians are alive, that they will definitely help him (but then why didn't he contact them?), and even presumes that they are still hiding in the same sewers as before, when it was stated at the end of 1-3 that they'd have to relocate, and he knows now that the planet is under imperial control. Still, he is not wrong, and despite most of the Mandalorians having died, their precious armor lie there even days or weeks after.
Plot hole: Moff Gideon can count on a plethora of forces (as seen in Season 2) and as a calculating villain who does not value at all the lives of his men, he should go and regroup. Instead, he engages Mando and the others firing at their boat, which if successful, would atomize the Child, making his mission entirely for naught.
Plot hole: Weeks if not months have passed since Mando has been on Nevarro, with the power shift and the Empire taking control. The Mandalorian community was small, but he finds the Armorer in the old lair that says that she will leave only when she will have salvaged what remains. Since 'what remains' is a pile of armor pieces, and she is carrying already a cart full of those, it appears absurd that she'd still not finished with that task, especially considering that we see how the smelting process is pretty swift (she melts an armor piece and shapes it into the signet in the space of a brief conversation!) and even if every single one of the Mandalorians left their armor behind, it'd be just a couple of carts' worth of metal.
Suggested correction: This entry presumes that the armorer has done nothing but collect armor pieces, and plans to continue doing nothing but collect armor pieces until she is finished. She never says that. She merely says that she won't leave until she is done collecting everything. She could be doing any number of other tasks she never says anything about because it isn't important. It is also never said when she started collecting armor pieces, it could have been just before we see her.
We can make all sorts of assumptions; she was grieving for a time, she had to go into hiding, she had to collect the armor pieces from various places? Fascinating, but if we do not presume anything, what we get is the Armorer (known as and for just that) salvaging armor (saying "I will not abandon this place until I have salvaged what remains") at a place established as raided a long time ago. What she had to salvage was meager (just a handful of Mandos) and does it fast.
In order to be a plot hole it would have to be impossible for the armorer to take this long to collect armor pieces. Since we don't know everything she has been doing off-screen, this doesn't count as a plot hole. You have to ignore all logical and reasonable possibilities to get to the point where this is a plot hole, and you list more than one in your reply.
I listed them because they are the kind of things we can assume to justify "Events or character decisions which only exist to benefit the plot, rather than making sense.", definition of plot hole in the website. We can make up all sort of background story, but nothing changes the fact that a character is at a place raided weeks prior and in the middle of performing a task that the way shown here is not going to take more than a few hours.
It's the "rather than making sense" part that this entry lacks. There are several reasons that make sense why this could take long, chief among them the fact that we don't know how long she has actually been collecting armor pieces. If, for example she said "I've been doing this since the attack", that would be one thing. She doesn't say that. She just says she won't leave until this particular task is done, not that it was her only task. She could have just started.
Collecting armor as specific task is something I find as such for the first time in your first comment. The attack happened shortly after Mando left, and the planet has been under a tight Imperial control since. Nothing leads to believe that the pile of amor is not salvaged but was brought back through some quest that stretched out for weeks until she finally decided exactly that day to start carting them to the furnace, which is what she's in the middle of when they arrive.
Plot hole: Seeing The Child in episode 2-1 minute 10, Amy Sedaris' character shouts "Thank the Force." Up to that point nobody seemed to have the faintest idea of what sort of mysterious energy Grogu was using. It gets worse in episode 2-3 when Mando uses as greeting for the New Republic "May the Force be with you", which is used later other times. With the concept of Force being this ingrained in people's culture, it's inconceivable that *everyone* is completely clueless about Jedi, especially considering that Order 66 with the Jedi purge happens barely 30 years before the events of the Mandalorian, and several characters such as Kuiil or Greef Karga were alive and active during the time when Jedis were powerful and part of the administration.
Suggested correction: There's a difference between seeing the Force used and knowing what it is and the common phrase "thank the Force" or "may the Force be with you." Plus, the Child is not a Jedi.
Not technically a Jedi, but he has been trained by Jedi and does those magical Force things that people would associate with Jedi, and would be perceived as such, if only people had any memories about them. Mando and Greef do not have the faintest idea of such 'magic' having ever existed, and Kuil has heard 'rumors' of it. Less than 30 years. Really, it's a common problem for all the Star Wars saga to some extent and it has been already debated to death. In this series nobody even seems to know the concept of Force in season 1, then in season 2 it pops up with random mentions.
The sayings are just customary more than knowledge of the Force. The Galaxy is big, with 3B habitable worlds, each having up to hundreds of millions if not billions of inhabitants each. The Jedi, at their peak and fall, were around 10,000. Many never heard of the Jedi, even less seen one. Find a remote village somewhere, and ask them if they remember the Atari.
Chapter 9: The Marshal - S2-E1
Plot hole: The Tusken raiders offer a Bantha to the dragon to make it sleep longer. To do, so they wake it up, which seems to defeat the point, but let's assume they know what they are doing and the dragon catches up on sleep later. Regardless, the dragon already ate one the day before. If it does not stay put even after just eating a Bantha a day before, it's hard to imagine how feeding it can be productive, considering that they all live in a desert and have just a literal handful of large mammals. The dragon should have eaten them all in a week, at that rate.
Plot hole: Mando's ship was completely wrecked, but two mechanics fixed it to top performance level and aesthetic pleasantness in a time shorter than it took for the Child to eat a small packet of macaroons.
Suggested correction: His ship was badly damaged, but mostly repaired by the Mon Calamari. The remaining repair work was less complex, but still took place over the course of several days. A space-faring civilisation being able to repair a damaged ship is not a plot hole.
His ship is literally falling apart (we see pieces falling off as it moves), the engines are barely functioning and looks like hell. It's not at all a mistake that a "space-faring civilization" is "able to repair a damaged ship", it is when the editing of an episode makes it look like two dudes fixed to pristine condition a wreckage in the same time it takes for a kid to munch his cookies.
Chapter 14: The Tragedy - S2-E6
Plot hole: Mando needs to make it to the top of the hill fast (he lost the ever important high ground, but he does not seem to mind). He would have a jetpack, but he left it behind. Now, everyone can be distracted and forget some piece of equipment and realise only a minute later (although it's a huge walk, and he has to climb, you'd think he'd remember right away). The problem is, even if Mando forgot the pack and realised only a minute later, the throwaway comedy intro of episode 2.2 showed that he can remote control the jetpack and call it back to himself.
Chapter 15: The Believer - S2-E7
Plot hole: The Imperial terminals have facial scan recognition...or just facial scan, really, since ANYONE regardless of being part of the army or not can just access any information of any level, as long as they have ANY face that the app can scan and identify as not being a known criminal.
Suggested correction: The facial scan prevents droids from stealing data from terminals.
And also criminals from doing that. It runs a check, as I said in the entry. Against "Any New Republic registry", even, which should disqualify also Mayfeld being a convicted felon, but that's another issue. Who designs a security system that does complex checks about who is a wanted criminal or part of 'the other side' but does not check if you are part of their side? Also, any low level trooper (or nobody, even the janitor) can just access any information of any level, including the location of their special forces cruiser.
Maybe it just checks if you're human. You never see non-humans as part of the empire. A lot of non-humans are as "subspecies" by the empire.
Chapter 16: The Rescue - S2-E8
Plot hole: In the previous episode, Mando and the others got a hold of the coordinates of Moff Gideon's cruiser, but this episode begins with them capturing Dr. Pershing in a shuttle, and after that they locate Bo-Katan and Koska and get them on board for the mission. How they found these people is unknown, and cruisers are not planets, they tend not to be stationary. Hard to imagine Mando and the others get into weird and complex subquests to get some help while Gideon at one point, which could be in just moments, could hyperspace in some other sector and leave them with no clue where to find him.
