I'd also just add.
When did OA learn to read English? She was a Russian child when she went blind, didn't get Herr sight back until much later...
If they weren't her books, who's were they?
If they were the FBI guys, what does he have to gain from framing OA?
Why, considering she pushed Hap down the stairs, didn't she follow him, kill him, take the keys from his belt and let everyone out? Oh no... Best to break a window and run... Even if she can't see... Yep much better idea.
Why didn't Homer kill Hap in Cuba (whaperever it was)? He knew hap was a Dr, they flew in a private plane that would be registered to someone, it took off from somewhere, the FBI or police could easily check Homers story as he knew the names of at least 4 other unconnected kidnap victims.
Front door open? And not once did anyone moan that all their stuff was nicked.
Parents finding the abandoned house at just the right moment?... How?
How did OA know what happened in the Hospital when Hap killed someone? In fact she's telling people what happened, any time she tells them anything that she wasn't there for... How does she know?
Why would a Sherrif, who had evidently dedicated yars to helping people, suddenly go against all that to help his wife?.... the only people who could help his wife would of been perfectly able to help her after they were saved and hap was arrested anyway?
Why didn't the homicidal teenage rampage killer, who had been killing people at random, shoot the dancers as soon as they stood up? Did he know they were about to have a dance off?
If they believed the 'moves' were intended to open a door to a different dimension..... Why did they think that a door to a different dimension would help whilst being shot at? Were they hoping the shooter would step through it? "Here you go Mr mass murderer, just pop on over to this dimension here with the stars and old woman.... She has a cuppa waotoing for you"
But.... My biggest bugbear, annoyance, problem.....
A kidnapper willing to kidnap and murder people, that is capable of building a huge and complex prison out of plexiglas, that's able to repeatedly sneak unconscious people in and out of planes and cars etc. With all that prep and skill they decide on NOT putting a microphone in the prison so he can hear what his prisoners are discussing... Even though he evidently can stream sound to them... Its fucking stupid.
