"Anatomy of a Psycho" has a premise that I'm pretty surprised that hasn't been copied to death by other movies - someone swearing revenge against those who were responsible for sending his brother to the gas chamber. There could have been a lot of perverse pleasure seeing judges, district attorneys, and jury members get snuffed. Unfortunately, the filmmakers don't seem to understand the potential they had. Despite a 73 minute running length, the movie is really slow- moving, and the central character only enacts revenge on three people - and two of those people are just RELATED to the people who were actually responsible for the central character's brother's death. With that in mind, the only way the movie could have been saved would be with unintentional humor. While there are some laughs here - miscast actors, bad acting, dopey dialogue - for the most part the movie is just drab and dull. If you want to see a more successful telling of the movie's theme, watch "Law Abiding Citizen" instead.
