Ugh, okay, I will give this movie three stars for being well made and well researched, but who really wants to see a movie about a cannibal serial killer?? The only reason I saw this was because I had to for a class I am taking at night and I thought maybe I would learn a couple of things about the human mind. I didn't, but I did learn that people can take virtually any subject and make it into a movie which is what these makers did. They don't just present doc**entary footage of Dahmer in court; they also have some scenes reenacted from testimony of the trial and Dahmer himself which are chilling to watch. It's very sad and very disturbing and I had to look away some of the time just to get through it. If you're someone who is faint of heart, I would say it's best not to watch this because you might have the urge to get up and leave. This is not a movie that serves as "entertainment."
