I saw District 9 during Comic-Con and it was
phenomenal. Peter Jackon introduced it with Neill Blomkamp. Plus Dominic Monaghan and Elijah Woods were sitting behind us (they weren't in the movie but I thought it was hilarious that Hobbits were sitting behind us!).
I only saw the first teaser trailer. My friends that went with me say that some of the money shots and action scenes are in the newest commercials and trailers; though it doesn't take away from the movie.
Not to give anything away but it starts off as a documentary and ends as a 30-minute Rambo action fest. It's clear that Neill Blomkamp got his Halo/video game fix in those last scenes. Hell, there's a gun that lift objects and shoots at people. It's Braindead meets Halo at times.
Let's put it this way: I absolute love Transformers 2 but District 9 does a better job of action. Transformers has dozens of car crashes throughout the movie that almost desensitized me. There is one car crash in the movie that makes me jump out of my seat and go "Holy %^#@!"
I can't wait to see it again.
