Factual error: The conversation between Taylor and Michelle tells us that school is over for the day and that Taylor talked to her crush at lunch. When the boy shows up at the bakery later, he and Taylor plan to meet at 3 that afternoon; if its before 3, they should still be in school.
Character mistake: At the end of the scene in the grocery store when Rachel collapses and people run to her aid, the camera pans out to reveal a sign that prominently reveals a sale on "Pop Tards" or possibly "Pop Taros."
Continuity mistake: When Dmitri and the doctor first try to get Vanessa to feed on human blood, the blood bag keeps switching from full to half-empty from one shot to the next. (00:16:05)
Character mistake: When Harlan Edwards collapses and Dr. Arcane tells them to clear his airway, one of the other doctors addresses her as "Dr. Cane."
Character mistake: Ryan tells Jack that Darius turned into a werewolf right in front of his and Micki's eyes. Ryan and Micki never witnessed Darius' transformation into a werewolf at all.
Revealing mistake: In brother Justin's padded cell, the far wall is obviously a painted backdrop. It even flutters when the orderly and doctor walk in! The only solid part is a couple of feet at the end, that Justin leans up against.
Super Nova - S1-E2
Revealing mistake: When Stan, Xev and Kai are walking to the Memory Chamber, they seem to walk out of a two dimensional line at the lower left into the scene. The set and green screen weren't quite synched.
Continuity mistake: When Adam gets angry at Joan in the art room because of the camera, his half-made sculpture is sitting on the desk. When he grabs his bag toward the end of the scene, he accidentally knocks it over, unbalancing it. But in the next shot it's balanced again, then suddenly it's unbalanced. This happens several times between shots, and can even be seen in one shot before he knocks it over.
Continuity mistake: Multiple times throughout the show, Kimber can be seen in quick shots with light pink hair (the same color as Jem's), when her hair color is actually a dark pink/red color. (02:00:00)
Coach Fussell's Lament - S2-E5
Continuity mistake: Chairface and Chrome Dome arrive at the Brianchild's house in the same car, but drive off in separate cars.
Continuity mistake: When we see Coraline in Mick's vision of when he was taking her dress off at a party, her tattoo is under one of her shoulders (I think it was her left one) but later on in the series we see Morgan/Coraline wipe off the make-up on where her tattoo is...on the opposite side.
Plot hole: During Ryder's report, as Bruce and company watch it on TV, the camera suddenly zooms in on Joker standing on a catwalk above Ryder, and none of the crew, especially not the camera man who caught the villain, makes a comment about this. They may have thought the Joker (or rather an impersonator) was perhaps a surprise gag in the show, but since this is supposed to be a serious documentary report, it is still strange that they wouldn't point it out.
Continuity mistake: In the final showdown between the Queen and Alice, in the wide shot, you initially see the Ten of Clubs standing beside the Queen, but when it moves to close-up, he has disappeared from her side, only to run into the scene behind Jack and Duchess moments later. (02:52:45)
Take Me out to the Ballgame - S4-E3
Revealing mistake: When the fat guys are running down to stop the bad guys, you can see the blue safety mat that they land on just after jumping. (00:37:00)
Turtles All the Way Down - S1-E13
Other mistake: When Dr. Lee and Dr. Evans are arguing just after Red Reality Michael and Green Reality Michael converse, Michael turns around and says, "Shut up!" but the closed captioning says, "Enough!"
Other mistake: Two Tiffs can be seen for a few seconds when King Dedede and Escargoon drive in.
Continuity mistake: When Josh has got out and they go looking for him, they find Aiden on a small bridge. From a distance he's got a very dark sweat stain on his shirt. In a closer shot it's faded to nearly nothing, and gets lighter/darker in different shots throughout the scene.
Visible crew/equipment: When Miss Hawk is speaking to Edward by the well, the boom mic can be seen in the top right of the screen.
Visible crew/equipment: When Nicky wakes up after falling asleep at the kitchen table, you can see the mike in the mirror behind her.
