I liked District 9 quite a lot. I wasn't really sure where it was going at first, but I still liked the slow build up at the start, made it feel more like a documentary or goofy news story until they started talking about 'after,' and you were kinda like "He did what? Did I miss something?" And then things get juicy.
Edit: BGC if you wanna go see Dist 9 again hollah at me <3 <3 <3
