Extremely well acted, particularly by the lead. Appropriately creepy and atmospheric -- as well as poignant and introspective. Makes a character out of a "monster". Examines Dahmer's struggle with his homosexuality and that struggle's basis for his sickness. Doesn't focus on the violence, and doesn't explore the cannibalism at all. Flashback structure works well. Liked the comparisions of his banal teenage years to the horrific current years. Would have liked a little bit more of an acknowledgement of how totally out of control this guy became. Cinematography is excellent at times -- but is bedeviled by some sloppy focus work. Again, the lead actor is topnotch. This is a work to be proud of.
