i thought it was ok. it's pretty straight forward and actually kind of generic. i wished they gave a better in depth look at who john holmes really was instead of introducing him as just "john muthafuckin' holmes." but then again it was a movie that investigates the wonderland murders not a bio pic on holmes.
i did see it myself, and it was weird. i didn't get into it but on the dvd version, you can actually see the real tape from the crime scene and it's just disgusting. crazyiness.
