I get that. I for one really liked District 9 and thought it was more than decent [IMDB 7.9 and 90% Rotten tomatoes] but always thought everything after was meh
District 9 was a decent action film, and felt like something different. Like Idiocracy, District 9's actual political commentary was very on the nose, but that didn't detract from it. It was very reminiscent of "Alien Nation" in some ways.
