The reason I watch any movie is for entertainment and this one certainly did that. I was largely unfamiliar with the Gacy story so I had no preconceptions. I found it believable and well acted. Judged on holding my attention and the scare factor I give it a 10. It surely deserves better ratings than it's been getting from the majority of the people who've posted thus far and I would not hesitate to recommend it to anyone looking for a way to spend an evening and enjoyable viewing experience. While it might not be exactly accurate in all details I did not watch it expecting a biography, just entertainment and that is what I got. So don't be put off by all the negative comments, see it and make your own opinion.
