Not very well reseached. Gacy's home location was totally wrong, he had a very ordinary bungalow. The film centred around Bobby and his parents, being the detectives. Gacy actor had the look but started laughing like the Joker. Nothing about the many victims or the detectives on the case. Cinematography was reasonable. The film reminded me of the much better Disturbia. Unfortunately not authentic at all. If this was a independent student project then I would have given it 2 stars.
