Zodiac (David Fincher, 2007) 8/10
There's probably more than enough material here to make a bingeable TV show. Crammed into a film it could be an overload of information, but they organize it well. The free flowing revelations give the film great momentum.
I did get a bit tired of having to watch Gyllenhaal's character get turned away again and again by detectives. At first it's understandable, since he's just a cartoonist with an interest in seeing the case solved. Eventually though it starts to feel like people assigned to the case are just too apathetic to listen, or they've resigned themselves to believing nothing that's uncovered will be strong enough to get a conviction. But I guess that's probably how it was, and how it is. It's a subtly damning film.
