The film is off to a slow yet mysterious start, but it quickly turns very suspenseful. It gave me gooseflesh at times! The father is a very timid and passive character and does not contribute to the story much. The film ultimately becomes very weird where the characters are truly completely mad. There's a lot that's difficult to understand, especially when we get to the twist. If she's hallucinating due to the medication, how does the hallucinations interact with the characters - especially the dead sister and stepmother? Towards the end I got confused with who was real and who was not, and who actually became someone else.
