When I first picked this movie up I feared it to be another cheap, poorly written real-life serial killer movie such as 'Gacy'. I was happy to find while watching it that it was actually a well done movie. Clifton Collins Jr. delivers a strong performance as Kenneth Bianchi, one of the two men responsible for the 1977 murders of many young women. His eerie resemblance to the real Bianchi really gives the film an extra boost of realism. Brittany Daniel gives a convincing performance as well, playing Samantha Stone, a psychiatrist who specializes in determining if a suspect is truly insane.
The movie lacks, though, when it tries to add an additional sub-plot in the story. This being Samantha's troubles with her partying, druggie, cheating boyfriend. This non-conclusive aspect of the story tends to use up time that could have been better used to develop Clifton Collin's character. Also, a factor that I felt was unneeded was the amount of nudity and sex in the film. Many shots of naked Daniel and other random couples having sex got a bit excessive at times, and tended to become redundant.
Over-all, the film was not badly done. I enjoyed a few neat filming effects and techniques in the beginning and other parts of the film. Good dialog, clever ending, and a good plot. 7/10.
*Word of warning- If you're looking for historical accuracy in this film you are not going to find it. It's very loosely based on the Hillside Strangler. The timeline is very far off and the events that occur are mostly made up for dramatic reasons.*
