It was okayish movie. For someone who can watch disturbing scenes, they can watch it but it is not for faint of heart. But quite a bit of plot holes so not as great as a movie.
*SPOILER ALERT*
It was so strange that the father would go to quite a lot of extent just for the daughter's lost doll, once when they were in the middle of vacation and second when they just left the psycho's house. I mean, it is just a damn doll, teach your daughters that they are not gonna get every damn thing just because they cry for it. So he loves his daughter so much that he would go to this extent just to retrieve her doll, but when she was being taken away, the parents didn't even put up a fight?
I get it, being frozen in a situation like that is understandable, but for someone who loved and spoilt their daughter so much, that plot was hard to let go. Even if they wouldn't succeed, they could have at least put up bare minimum of a fight, but they didn't.
