David Fincher, who previously directed some of the best films off all time, like Se7en (1995), and Fight Club (1999), comes back with this horror movie, based on true events. It's quite long, but the film is well made and sticks pretty well to the true story, feels, in a way, like a documentary. It's surprising how the film's dialogue can be very tense, suspensful and very scary, much more than the death scenes. The film spends more time developing, following the characters and shaping their personality and role in the story. Bottom line, this is an other achievement by David Fincher and makes you wonder who was, or is, and where the hell is the Zodiac now? Recommended !!
