This is one of several movies that have been made about the famous Zodiac killer. There's not a lot of action, mainly a character study. The movie focuses on 3 guys searching for clues about the Zodiac. One is a detective, one is an editorialist at the paper, and the other is a cartoonist at the paper, Robert Graysmith. The story centers around Graysmith as he seems to be obsessed more than any one and spends lots of time trying to decipher the Zodiac's codes. They come up with a prime suspect but are never able to get enough evidence to bring charges. The movie is based on a book Graysmith wrote.

FINAL VERDICT: If you've seen another movie about the Zodiac, then you know what happens. This is nothing new. But, it is too long.
