A few scary, brutal murder sequences, surrounded by a lot of triviality and talking. The pacing is stagnant (there are many scenes that could have been trimmed) and the story is absurd (a girl falls off a swing, hits her head, develops amnesia and then becomes a homicidal psychopath out to get the nurses who treated her!!!). Footnote: I don't think I've ever seen the police being more stupid and inactive than they are in this movie. (*1/2)
