The basement scene is one of the most tense experiences I’ve ever seen. People say the running time is too long but 2 hours and 42 minutes is needed to condense all the relevant details of the case into a film. Every scene serves a purpose to shape the intended story and I think David Fincher aced it. You feel like you’re a part of the investigation. The fact that the Zodiac Killer was never identified is such an unsatisfactory situation.
