Hasn't been much strictly genre wise.
Insidious was pretty good. Really the only true genre movie from 2011 I've seen.
Hobo was awesome, one of the best of the year for sure.
Sucker Punch would be my fave flick of the year overall so far. SO underrated. The critics scared people away with their closed minded assery, and once it hits DVD, people will kick themselves for not seeing it earlier.
Unknown was solid. It was pretty much a rehash of Bourne Identity, but Liam Neeson was awesome, so it worked.
Hanna was fantastic. It felt a little unfinished at points, but overall, twas a great ride.
Fast Five was pretty mindless. Since it's pretty much Ocean's 11 meets Italian Job, it was good for what it was. Pointless action, shitty dialogue and camp acting.
Battle L.A. was okay. Better than I was expecting. I figured it would go the cheese disaster flick route, but they kept towards the more "serious" side, and it kinda worked.
That's pretty much all the 2011 releases I've seen this year. Not much left at this point either, since EVERYTHING and it's brother is in $D, er, 3D. Cowboys vs Aliens I'll check out (mostly since it's not in 3D). Cabin In The Woods in Oct and Apollo 18 in Aug are musts. Don't Be Afraid Of The Dark should be good, and The Tunnel is a given (since it's free.... until I buy the DVD down the road). Oh, and Troll Hunter, if it EVER gets some kind of legit release. Probably a few others I'm either forgetting or haven't been announced yet.
