SilentDawn’s review published on Letterboxd:
Zodiac is so disturbing and unsettling that the first time I watched it; I started shaking. It's that powerful.
The Awesome: David Fincher at his peak, his direction here is flawless and mind-blowing. If you don't believe me, watch the opening sequence. All the acting; from Jake Gyllenhaal to Robert Downey Jr tell this fascinating piece of history with true authenticity. The killings are graphic and brutal, frightening and chill inducing. Yet, they aren't gratuitous; and they add a layer of potency to the story.
The Bad: If you hate length and dialogue, skip this one. If you can brace though the 3 hour run-time and incredible conversations though, you will uncover a true gem of cinema.
Overall, Zodiac is Fincher's finest achievement and easily one of the best films of the 21st century. Dare I say it, even one of the greatest films of all time.
