This movie is said to be suspenseful, but I would like to ask, there is nothing worth learning about medicine in this movie. If you follow the protagonist's thinking, then the hospital and the police are 100% evil. Then the only bright spot in this movie is that at the end there is a reverse male protagonist who discovers that he is in a mental hospital, and the police are the only ones who are just. This is the only selling point of this movie. For the rest, I think it is a very ordinary suspense movie.
