Not for the ADD generation.

Rating: 8/10 (13 March 2007)

Warning: This film is flawed.
That said, I thoroughly enjoyed Zodiac. Robert Downey Jr. was the stand-out of the cast, but other than Gyllenhall (who should have just quit after 'Donnie Darko') the cast as a whole was fine.
As has been said, 'Seven' is better, but we've all seen that flick about 400 times, right? Fincher was on point and his refusal to pick one character as the lead is a Fincher trade-mark (see: Seven, Fight Club).
Fincher succeeds in holding the (mature) audiences attention and manipulating our emotions whether through our frustration as suspects (whom we are convinced are the Zodiac) slip through our fingers, or through our fear as the killer(s) closes in on his prey.
Some will argue that this movie was 'too long', but this complaint will mainly come from the 'ADD generation' raised on music videos.
The soundtrack was great and very moody. Donovan's 'Hurdy-Gurdy Man' being the creepy stand-out.
All-in-all this movie delivers and is the best thing in theatres right now. If you get bored easily, just go watch '300' instead.
