Amazing.

Rating: 9/10 (5 December 2012)

This is simply an excellent film. Besides the length, the only bad part to this is that David Fincher had to fabricate the friendship between Robert Graysmith and Paul Avery. It would be a much much different movie if those two had only been coworkers or had disliked each other. But aside from that, it's a fantastic film. The casting is amazing, with such names as Robert Downey Jr., John Carroll Lynch and Philip Baker Hall among others.
I know this is based on real events and all but I'm not easily scared, so I didn't find any of it frightening. But then I did watch it when I was ten or eleven so that might be the reason. It's a in-depth look at a psychologically off-kilter time, and I highly recommend it.
