I actually love this movie.
No trolling. :)
I hate political correctness in general and I find this movie hilarious, from the crude jokes, to the little details, to the whole concept.
And in the end, I have to say it's just brilliant to make a movie from an alien race's perspective, deem that race as "far far more intelligent" than humans, and portray humanity as a problem in the universe. Actually not even a problem, because humans are far too small and insignificant to put up any resistance, rather have the alien race help humanity in a way we never considered before, and if we had considered it (seriously), we would find downright offensive!
