Perturbada

I am actually a practicing clinical psychologist, and let's face it. The premise of this film is ridiculous. If you're to have a good time at this one, you'll have to set aside any idea of real mental health hospitals (even private ones) and just go with the story. About twenty minutes in, I stopped saying, "But that's wrong!" and "That's not right!" and just let the movie be a thriller/fantasia on the paranoid nightmare of involuntary commitment. After that, I thought it was quite an enjoyable movie.

If you require realism, you'll probably hate it, despite good acting, good pacing, and an enjoyably twisty story.
