I saw District 9 yesterday. I think it was the first time I watched a sci-fi movie where the fx where transparent. Usually I have a hard time believing that fx characters are actually in the scene, with the exception of Gollum in The Lord of the Rings, and generally I just get distracted by the way they move or look. I guess good fx are the ones that don’t look like so, I believe District 9 achieved that brilliantly.
Apart from the fx, I enjoyed this one a lot, I love sci-fi movies that don’t bother to explain the whole story and just leave us imagining what happened.
