This film sucks. If you really want to learn about the zodiac killer, the best thing to watch is "This Is The Zodiac Speaking" documentary. There aren't any good zodiac killer films sadly. A movie came out in 2007 called "Zodiac" with some fairly successful actors but the movie was awful and quite boring. The documentary is the way to go which is told by real victims, police officers, and even the female dispatcher who took the zodiacs phone call. Very creepy.
