I'm two and a half hours out from finally having seen it and I can't stop turning it over in my head. This is astonishing film craft. Every little piece is in exactly the right place. Real characters, real performances, with not an ounce of showboating, on-the-nose nonsense. The plotting is nail biting in the most insidious, unnerving way. Bigelow is masterful with suspense. And thematically? Jesus. I could spend months trying to unpack it. It's so thoroughly baked into the characters and the plotting and it never tips its hand. It plops you smack dab in the middle of the grey. It's not going to hold your hand and tell you how to feel. Here it is: you deal with it. It's the abyss that stares back into you. You could write a college thesis on the last shot alone. This is filmmaking for grown ups.
