You see, "Maniac" isn't necessarily what you would call a bad film. It's filmed decently, Tom Savini's gore effects are good and Spinell's and Munro's performances are very good. But "Maniac" fails at being an entertaining experience. It's neither a good horror movie (only somewhat tense scene is the one in subway station toilet) nor a good psychological movie. In fact, whole story about Frank's relationship with his mother and Anna feels just tacked on to give some explanation to his murders. It's worth to mention "Goin' to a Showdown", a song featured in the movie, which is quite good. But other than some positive things, "Maniac" is boring and unpleasant (not in horror, but in entertainment sense) movie that I recommend only to horror movie veterans looking for a piece of genre history. Everyone else, avoid it... 5.5/10!
