Steve Moyle’s review published on Letterboxd:
For me this is probably Fincher's best, it's simply personally the one that's impressed me the most but people could obviously argue his truest masterpiece to be something else. It tells the story of the long hunt for the notorious Zodiac killer who was never found and what we have is a truly perfect film and I have no problem calling it that. David Fincher is always very detailed and obsessive and for me his style is more fitting then ever with Zodiac, the direction is extremely impressive. I've seen it a few times now and each time it just grips me right from the start with it's dark and beautiful noir like cinematography and eerie quietness. The actual case had no definitive answer so naturally neither does the film and it's very much an in depth look at the case and the people who were most obsessed with solving it and each character stands out in different ways. It has a perfect cast and is 157 minutes without a wasted second, I'm always just so absorbed with it and it manages to creep you out and keep you on the edge of your seat as an anxious mess the entire time, what an achievement.
