I picked this up after reading "The Last Victim" and being totally fascinated with Jason Moss's story. The film leaves allot of details out which i had a hard time overlooking when i first saw it. Watching it again a couple of years on it really isn't a bad film now that the details of of the book aren't so vivid. William Forsythe does a great job portraying Gacy and Jesse Moss (no relation) is good as well. I would definitely recommend reading the book but also give the film a try as well.
