Deliberate mistake: The "flow" from Fred (Rachel's brother) urinating while strapped to a chair was not what would be expected. His pants would absorb the urine, so urine would not flow to the floor like from a faucet or large streams drip straight down and form a puddle beneath him. (00:57:06)
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. (00:19:11 - 00:19:47)
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)
Deliberate mistake: Noel's mother was removing a tray of cookies from the oven as Noel was walking into the kitchen. Noel was able to pick up a hot cookie from the also hot tray without burning his fingers, but he did burn his tongue after taking a bite. Even IF Noel could touch a cookie without burning his fingers, a hot cookie is not easily removed from the tray and it would collapse - not hold its shape (unless overcooked to a crisp). (00:16:43)
Deliberate mistake: A shot of the pile of ashes from the fire wherein Cassie's body was essentially cremated showed Nina's half of the broken heart necklace sticking out ABOVE the ashes, which would be impossible. Also, a metal charm on a chain that was around Cassie's neck would not survive the huge fire or be totally clean and unscathed.
