Zombieland, was good, great even, but by no means the best. District 9 looks good, I have yet to see it though. My vote goes out to Snatch. If you haven't seen it, stop what you are doing and go and rent it (orrent-tay) and watch it. Because it is amazing.
I really don't want to spoil it. If you care so little about movies that you don't want to see it, just google it. There is pretty much no way you can't like it.
Good grief, you people don't know good movies. Forrest Gump, Silence of the Lambs, Donnie Darko, Castaway, just to name some of my faves. Let me emphasize Donnie Darko. It is freakin amazing. Incredibly hard to understand, but once you get it, you'll just fall back in your seat.
