Deliberate mistake: When the kids are about to jump start the trap Phoebe hides behind the school bus door. Half a second later, when the trap opens, she's nowhere to be seen, not even jumping or stepping inside the bus. Then half a second later she has managed to get inside, turn around and protect her head while the bus windows burst. It all happens in real time for their hairs are still fluttering. It sure paces up the scene, but it's really awkward.
Deliberate mistake: The suit, rather than using many large cameras, should be created with many imperceptibly small cameras in between monitors. We need monitors to see what is on the other side of the suit, not camera lenses.
Suggested correction: The monitors are on the inside, behind the cameras.
Deliberate mistake: The images of Spencer's face in the driver's side mirror are not realistic for someone in the driver's seat. The driver's side mirror is angled outward (perhaps 60° beyond a typical angle), but his face is perfectly reflected. When Spencer starts smoking, the viewer gets a glimpse of a figure behind his car. Spencer senses something and his face is shown backwards in the mirror, as if he were crouching outside a few feet from his car. Spencer does not use the more practical rearview mirror.

Deliberate mistake: The oval mirror was in a depressed wall yet was able to reflect a window within the adjacent depressed wall. (00:18:23)
