I Dream of Jeannie Cusamano - S1-E13
Revealing mistake: When the shrink locks the door on Tony, they argue and she calls the police. When she finally calms down she approaches the door to unlock it but you can see the door move before she ever sticks a key in it or touches the knob. (00:25:20)
The Dark Network of Etemon - S1-E15
Revealing mistake: Watch the scene where Biyomon and Palmon are eating. A Pagumon passes, Biyomon turns her head and then has two beaks. Obviously a frame overlap.
Destiny (2) - S1-E22
Revealing mistake: Throughout the scene where Max interrogates Pierce, the projector changes slides at irregular intervals with no one touching it. (00:22:50)
Revealing mistake: During Kendrix's morphing sequence you can see that the editor did a poor job photoshopping the Ranger helmet and you can still see the white edges of whatever photo they used. It should be tight to the Ranger's helmet and costume like the rest.
