David Fincher always makes really well-made movies. The very techinal aspects of all his films are top-notch. The camera is very smooth, the colour palette is again very stylish, the score and soundtrack haunting and the acting is superb. David Fincher knows what he is doing. His films always suck in the audience even though not much is happening. This story for instance is based on the true story of a cartoonist getting obsessed with the Zodiac killing that took place in southern California in the late 60's and early 70's. When you start to create true stories, it gets harder to follow the classic Hollywood three-act structure. This film starts off very interesting with all the characters getting equal amount of screen-time and the creepy zodiac written letters begin to start coming in. Down the stretch, it starts to become a bit of a bore when the zodiac killer becomes absent in the story. While I can't really fault the filmmakers for this because this is a true story and the filmmakers were trying to depict the story as real as possible but it's something to take note of before you watch it. This is one of those films where many little clues are dropped here and there throughout the film and while many of them might fly under the radar or you may not remember all of them, they all come back at the end to make an impactful ending. Overall, this is a really well-made film. If you like David Fincher's other work like Gone Girl and the Social Network, I think you will enjoy this one.
