There's a lot of R-rated content in this one, mostly language. With the exception of only two characters, everybody cusses about every other sentence. That includes an obscenity, several "S" words, and an obscene gesture. The movie isn't very violent for the most part, except for one really gross scene. When one of the characters is found dead, the other two don't know that he was attacked by alien bugs. The audience doesn't know this either, until one of the bugs crawls out of his face. I was surprised this movie could keep a PG-13 rating after all that.
