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
Continuity mistake: When Mando is talking with the one eyed mafioso, he tells him to enjoy the entertainment gesticulating with his left hand. At the cut, he's shown from behind lowering his right hand. (00:05:05)
Chapter 9: The Marshal - S2-E1
Continuity mistake: At the end of the fight with the two Gamorreans (just after the reaction shot on the Child), one of them swings the axe to the torso of the other, who takes a direct hit under the raised, weaponless arm. Which is the left, then the right. (00:05:10)
Chapter 9: The Marshal - S2-E1
Continuity mistake: When the cyclopic mafioso shoots the competitor, the gamorrean falls back straight, but in close-up he's crashing on the mat turned left. (00:05:50)
Chapter 9: The Marshal - S2-E1
Continuity mistake: Mando ties the hook cable at the base of the post but when he talks to the monocular scumbag the rope is just coming down straight with no trace of the diagonal part that ties it to the base - you can notice it distinctly well when he blasts the lights away and the whole top part of the post is perfectly lit. (00:07:35 - 00:08:20)
Chapter 9: The Marshal - S2-E1
Continuity mistake: Mando is talking to the bartender. When he grunts "See for yourself" one of his pigtails moves from the front of the left shoulder to the back. (00:14:25)
Chapter 9: The Marshal - S2-E1
Continuity mistake: When the mysterious Mandalorian is sitting at the table once he set the liquor and glasses on it, the bartender changes position during the cut that happens mid-action. (00:15:10)
Chapter 9: The Marshal - S2-E1
Continuity mistake: When the cantina is starting to tremble thanks to the dragon ex machina, the bartender on the background turns towards the rumbling twice in two separate shots. (00:17:05)
Chapter 9: The Marshal - S2-E1
Revealing mistake: The Marshall and Mando have a casual conversation between speeder bikes, even when the sound the engines make at that speed is deafening (there's a sample of it during the establishing shots!) and the sound of their words wouldn't propagate properly. He also must be wearing an invisible Mandalorian helmet or use beskar-based gel, because his hair barely moves. (00:20:25)
Chapter 9: The Marshal - S2-E1
Continuity mistake: During the flashback of Cobb's revenge, it's obvious that the reaction shot of him taking a hit that is absorbed by the armor is edited in introducing an artificial pause into the pace of the action; the person that is slumping after being hit is still falling after his long dramatic pause in close-up. (00:23:50)
Chapter 9: The Marshal - S2-E1
Continuity mistake: In the campfire scene, the Tusken raider passes Cobb Vanth the foul looking fruit thingy, which looks broken in a different pattern in the various shots. (00:27:30)
Chapter 9: The Marshal - S2-E1
Continuity mistake: When the angry Tusken says that the locals steal their water and then insult them by not drinking, Vanth is holding the black melon with one or two hands depending on the shot. (00:27:45)
Chapter 9: The Marshal - S2-E1
Continuity mistake: The Tusken raider that was herding the sacrificial Bantha is eaten by the tapeworm dragon and the others look at the scene through Toro Calican's binoculars. The straps on the binoculars are dropping straight in one shot, tangled above it in the next. (00:30:30)
Chapter 9: The Marshal - S2-E1
Character mistake: Cobb Vanth says that he's never seen anything but the dragon's head and had no idea about the size of the dragon...but at the beginning of the episode we could see the beast pass through town (conveniently right in the main road without damaging anything else) and its enormous lengthy body was perfectly noticeable. (00:31:20)
Chapter 9: The Marshal - S2-E1
Continuity mistake: When the clumsy Tusken drops the explosive causing the ire of the villager, the reaction of Mando and the Marshall comes from two separate takes; their hand positions are different. (00:34:40)
Chapter 9: The Marshal - S2-E1
Continuity mistake: When the villager is arguing with the Tusken, one of his buddies is holding a shovel and looking all menacing. The shovel is held in a different position each shot. (00:35:50)
Chapter 9: The Marshal - S2-E1
Continuity mistake: The villagers and the raiders united just got near the cave. One of the Tusken raiders is by the cave checking for vibrations. He has his rifle in the right hand, then after a cut to the Child he's got the rifle in the left. (00:37:35)
Chapter 9: The Marshal - S2-E1
Other mistake: The acid the dragon spits is purported as highly corrosive, literally melting people, however Mando is unaffected by it despite being bathed in it. His armor might be Beskar, but there are plenty of spots (those that his enemies constantly seem to miss) that are not. He should be at least in some discomfort and in need to change, and not carry around his neck a cape soaked in venomous dragon vomit.
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.
Chapter 10: The Passenger - S2-E2
Continuity mistake: When Mando puts the jetpack down, the shadows on the ground are inconsistent, pointing to the right either towards him or the Child. (00:03:50)
