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.
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 10: The Passenger - S2-E2
Continuity mistake: The giant spider punches at least two holes in the cockpit glass, the legs going through it all the way, but there are no holes visible in the rest of the episode, nor when the camera is inside the cockpit, nor when he 's talking with Dave Filoni and his buddy and the spider queen is slumped dead, just by the spot she was assaulting. (00:31:50)
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.
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 6: The Prisoner - S1-E6
Plot hole: Mando's ship appears in front of the X-wings, but they ignore it entirely without even acknowledging its departure. Considering they have strength in numbers and are chasing a fugitive and acting with extreme prejudice, it makes no sense. (00:36:40)
Chapter 7: The Reckoning - S1-E7
Revealing mistake: There's some sleight of hand involved when Cara gets her cup of tea from the repurposed IG-11. Maybe it was costly to have the animatronic arm working to the point of actually supporting the cup and hand it to her, so pay attention to what Cara actually does; Gina Carano is ALREADY holding the cup, taps the mechanical hand with it as if the fingers just released it from their grasp, and retrieves it. (00:11:50)
Chapter 14: The Tragedy - S2-E6
Audio problem: In the "Previously" section, Mando is shown telling Ashoka; "Bo-Katan sent me to talk to you." But the actual line in the previous episode was "Bo-Katan sent me. We need to talk." (00:00:20 - 00:16:20)
Chapter 1: The Mandalorian - S1-E1
Other mistake: The laser cannon punches decent sized holes into the columns and even cuts through the thick metal of the door (and look with what ease), but it is shown hitting the droid at least 4 times never managing to do any visible damage to it. When at the end of the battle they talk about the 'wound', it's not in one of those spots. (00:33:30)
Chapter 16: The Rescue - S2-E8
Continuity mistake: In the opening recap of the episode a scene is shown where the Mandalorian is sending a speech to Moff Gideon, which was originally from the end of episode 15. In episode 15, he says "He (Grogu) means more to me than you will ever know," but in the recap he says "It means more to me than you will ever know."
Visible crew/equipment: When Omera brings The Mandalorian some food and says how she noticed he hasn't eaten, a boom mic can be briefly seen just above her head. (00:16:33)
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.
Continuity mistake: The door of the bar Cara Dune is hiding in, is blown out of the doorframe by a trooper, but later it's back and fully repaired, and IG-11 closes it. (00:17:21 - 00:18:31)
Chapter 6: The Prisoner - S1-E6
Continuity mistake: The droid arm with the blaster on Mayfeld's back switches from his right side to his left side between shots. The arm is on his right side throughout the entire episode, so they probably flipped the footage of that one shot, causing the arm to be on the wrong side. (00:30:37)
Continuity mistake: When IG-11 is making its way through the city with a cartoonish trail of explosions, Greef Karga is having a drink. There's a sudden cut, and in the second shot the glowy liquid in the bottle is bouncing around very noticeably as if the bottle (or the whole counter) was just moved/knocked, which did not happen in the previous shot. (00:15:45)
Continuity mistake: When the nerdy Moff namedrops Mando and Greef's real identities, the shots from the waist up are mirrored; look at the position of the buttons on his Darth Vader-esque chestplate. (00:08:30)
Continuity mistake: After the comedy skit with the two scout troopers is over, the ground in front of Moff Gideon is in the shade or sunlit depending on the camera angle. (00:06:00)
Continuity mistake: The Scout Troopers have finished their shooting game. One of them gets up and the other looks bored (and annoyed because he does not get to see the 'package'). He is leaning against the bike's handle, or not, depending on the shot. (00:04:10)
Chapter 7: The Reckoning - S1-E7
Continuity mistake: When the two bodyguards approach Greef Karga and the others from behind with the intention to shoot the good guys, the green guy has his pistol already fully raised, but conveniently when Karga double crosses him the gun is lower. (00:24:45)
Chapter 7: The Reckoning - S1-E7
Continuity mistake: When Greef Karga approaches Mando's party apologizing for the far away rendez-vous (French is trendy even in space), the leftmost guy in his group has a long axe-like weapon he holds in his left hand, right hand at the reverse shot, let again in the rest of the scene. (00:17:20)
