It's tough to make a movie about a serial killer that was never caught. ZODIAC is a surprisingly good film about it, at least for the first 2 hours and 30 minutes.
Alas, in the last ten minutes, they try to solve the crime... in title cards... and then admit that DNA evidence has disproved their resolution. Meaning that at the end of the film, you're left feeling unresolved.
The rest of the film in intriguing, although the film's makeup is so bad it's distracting. The cast is excellent, and the script is very good until the final third, when it starts to border on being a parody of itself.
Wait for video.
