There was a whole slew of these serial-killer bio-pics released in the early 2000s. I'm pretty sure all of them were released direct-to-DVD and like most every other horror movie made in that time period they mostly all sucked. This one is no exception. It at least gets many of the facts of Dahmer's life right with a reenactment of his very first killing, mummified heads in boxes, arguments with his dad and some gay-bar rape shenanigans. At the same time it omits pretty rudimentary stuff like cannibalism and Dahmer's big vat of acid he used to dispose of body parts. For a movie about some pretty gruesome murders there is very little blood or gore in this thing and plays more like some 90s indie drama about a lonely weirdo looking for some gay love. It also has a mostly sappy boring soundtrack that makes me want to take a nap. To be fair I've only viewed the R-rated disc of this movie and there's apparently an unrated version out there which might make things at least a bit juicier if not any more exciting.
There is what is supposed to be a way better, and way gorier, Dahmer flick called THE SECRET LIFE OF JEFFREY DAHMER (1993) which I unfortunately have never seen but I will have to rectify that soon.
