Continuity mistake: Lady Raven arrives at the Coopers' place and starts talking to the wife. Cooper's watch is set to 1:35. An instant cut later it's set to 1:20.
Continuity mistake: When Jamie hands Cooper the box cutter, it changes position between shots.
Continuity mistake: Cooper is back to his daughter after his bathroom break. He tells her that he met the mother of one of the friends she has a complicated relationship with. He holds her close, grabbing her shoulder. But meanwhile, Lady Raven on stage starts talking, and the next shot, father and daughter are in a different position already.
Plot hole: The movie establishes that the FBI has a list of suspects thanks to security camera footage from the area where the victims were found. "A red headed man, two African Americans above average height, a white haired man." Then, the zinger; "a man in his 30s with a tattoo of a rabbit or an animal on his right arm", which of course is our guy Josh Hartnett. We see the tattoo, and it's a little doodle of a sheep, about a couple square inches big, below his wrist. That doesn't really make sense; if they have security footage with that level of detail, one wonders how could the rest be so vague. The next entry mentions "a male with a scar on his jaw", which is even more absurd. Either the security cameras picked those details up along with the suspect's full appearance and mugshot, or they just can't know with such certainty (if the suspect was masked or concealed in any way, then they would know for sure it was the killer and wouldn't be chasing people with wildly different appearances).
Continuity mistake: Inside Lady Raven's limo, the protagonist's daughter changes seats briefly to go hug her dad. She then grabs the swag bag and asks her idol, "Uhm, can I?" to move back next to her. Saleka Shyamalan says "Yeah" and gestures to her, but she does that looking towards her right (left side of the screen, which would make sense only if Riley were sitting to her father's left. She is seated at his right).
