Plot hole: In the very first episode, the Wu Assassin (who hasn't even been properly trained yet) is fast enough to dodge bullets, that appear slowed down to him, leaving a trail behind them. At no other point in the series does the assassin exhibit that sort of speed and reflexes - in the penultimate episode he definitely can't dodge bullets, although the villains use automatic weapons so the comparison is in part unfair. It sure seems that he has been 'nerfed', or that he was accidentally written too overpowered in the first episode.
Suggested correction: I watched the scene and there's nothing to indicate he's seeing the bullets appear slowed down for him and he's not dodging bullets from his incredible speed. He's just zig zagging in a narrow hallway as he approaches the shooter, causing the shooter to miss because he doesn't know where to fire at (not that he was a skilled shooter in the first place.) He didn't dodge the first shot, he just reacts to a bullet going by him so closely. The bullet trail was a visual effect for the audience.
He's literally following the first bullet with his eyes, turning: the trails are there for the audience but it's a fact that he turns his head to the first bullet and dodges the second moving out of the way once it has been fired already, and he moves out of the way of the third once the shot has been fired as well, I call that incredible speed! That scene looks way more matrix-y than it had reasons to be compared to the rest of the show, imo. And he has not been trained yet. Valid point that the guy was most likely a terrible shooter and the last couple of shots are bad misses to begin with, but the bullet speed is the same anyway once a bullet has been fired, regardles of who fired it. I upvoted your comment though because I appreciate feedback and if your different perception of the scene is important.
Continuity mistake: Kai, in the kitchen, is putting the finishing touches to the dish, sprinkling it with peanuts. The peanuts bowl changes position and then disappears completely from the prep station between shots. (00:04:15)
Continuity mistake: When CG is done talking with Lu Xin at the diner, she grabs a glass and drinks from it. During this action, Lu Xin is eating a fry in the first shot, but in the second he's waiting on her with the left hand on his clenched fist. (00:26:20)
Other mistake: After the initial flashback, the action is set at night - yet Kai's phone indicates 12:52 PM at home and then 1:53 (PM, in Lu's text message) at Uncle Six's. (00:05:20)
Factual error: Kai checks out his phone repeatedly and the date indicated is "Wed, Aug 22." Just a scene after, Jenny is shown with an August 2019 calendar in the background. August 22 2019 was a Thursday, not a Wednesday. (00:06:00)
Continuity mistake: Agent CG is having her morning jog and there's a sizeable sweat spot on her top. That is, until she gets to the park for her scene with Mr. Master of disguise himself captain Fletcher: at that point her sweat stain reduces size considerably. (00:09:45)
Continuity mistake: Kai tosses the rock fragment next to the dagger, but in the following shot the distance between the two has increased dramatically. (00:31:50)
Fire Chicken - S1-E3
Continuity mistake: Kai and Jenny put aprons on and start chatting. Behind Kai, a person is carrying a tray, then still has to pick that same tray up, disappears, reappears, etc. (00:13:10)
Fire Chicken - S1-E3
Continuity mistake: As the Triad goons pulls over their black van and kidnap the helper of Mr. Young, some passersby disappear between shots and others change position. (00:30:00)
Fire Chicken - S1-E3
Continuity mistake: Opening her last stand against Uncle Six's henchwoman, Jenny tosses her a bottle of oil. On the wooden chopping board there's a big knife, that disappears once Jenny waves the frying pan around, re-appears a moment after, and so on. (00:32:00)
Fire Chicken - S1-E3
Continuity mistake: When CG pours a drink to the retired agent saying "C'mon, Jack", Jack keeps his hands off the table in the close-up, while he's holding the glass as she pours in the shot right after. (00:36:20)
Fire Chicken - S1-E3
Plot hole: Unable to locate "the bald chef", Uncle Six orders his men to bring him all the bald chefs of Chinatown. And they do! His goons round them all up, in a single sweep. They fit in a little van. So...in the whole San Francisco Chinatown, over 30,000 inhabitants, there are only literally a dozen bald (or balding or shaven, when you look at who they got) guys working in a kitchen.
Revealing mistake: When the protagonist and Uncle Six battle on top of the escalator, Six gets thrown off, landing downstairs. Very much like a pro wrestling Irish whip, it's quite noticeable how the victim is running towards the move before he gets pulled, with a cut to try to hide the lack of any push from the other hand or forceful twist. (00:12:15)
Continuity mistake: Washing Kai's wounds, CG tells him "I need to know more." Fresh blood trickles down her cheek, but has vanished in the following shot. (00:17:30)
Plot hole: CG is worried that if Kai phones her, he might blow her cover. Kai is no suspicious character and it's established that they know each other after the windshield errand. On the other hand, she engaged in a fight with several thugs and the very boss of the Triad who all have seen her, her cover should be pretty much blown already at that point. It's also quite funny how she made sure to meet with the Captain in secluded locations during long jogs, but then kept in her desk police files about the suspects! Some undercover cop.
Codladh Sámh - S1-E5
Continuity mistake: In the swordfight set in 1519, Ying Ying offers the Monk Piece to her adversary. Depending on the shot, she is simply holding it in front of his face, or also pinning his arm down with her own. (00:10:10)
Codladh Sámh - S1-E5
Continuity mistake: Kai is explaining to the gang the whole Wu story. When CG says "He's telling the truth" she is leaning against the table grabbing the edge in the back view, but leaning on it with her flat palms in the other shots. (00:13:00)
Codladh Sámh - S1-E5
Continuity mistake: CG is waiting for Lu Xin in a Jeep Wrangler, but later on the side mirrors and interior belong to a Benz G-Wagon. (00:29:19 - 00:31:59)
Codladh Sámh - S1-E5
Continuity mistake: Kai hands the note to Mr. Young: the old man holds it between index and middle fingers, but with his thumb in the reverse shots. (00:39:45)
Gu Assassins - S1-E6
Continuity mistake: Lu Xin is downstairs playing with his lighter. The first shot ends with the lighter held still with the decorated side towards him, while the following one has the the solid gold side face him. Moreover, when Jenny sits down he goes from having both hands on the lighter, to one hand on his bicep. (00:18:30)
