Good ones I've seen lately:
The Human Centipede 2 (Full Sequence): Don't care what anybody says, I enjoyed the first movie and didn't know how they could possibly make a successful sequel. They did. Amazingly depraved.
13 Assassins: A good old fashioned Samurai flick a la Seven Samurai, updated for Miike-style violence.
Attack the Block: One of the best films of 2011 that you've never heard of.
Suspiria: The most beautifully shot horror film I've ever seen, and genuinely terrifying too. Overtook The Shining for best horror flick I've seen.
Red State: Hats off to Kevin Smith for trying something completely different, and pulling it off. And a spellbinding performance by Michael Parks.
The Room: I say this is my favorite movie ever. Be warned: it's terrible. But so terrible that I am always entertained watching it.
