--SPOILER--
Overall, I liked the film but I didn't like the twist at the end. Taylor Schilling's character's acting is way too good for someone who is not an actor. It feels like it was leading up to something great and fulfilling, but then the makers of the movie went screw it and abruptly ended it by saying "oh she was just acting the entire time and thought Ray was in on it as well."
Tldr: The movie left me wanting more.
