This movie is a nonsense/spoof comedy, in the lines of The Airplane or Naked Gun, but it doesn't even come close to this two, because it lacks originality and a little more intelligent jokes, rather then just throwing you with the same old easy jokes.
You can figure out some references to other movies, from the top of my head I identified Dodgeball and Rocky, so you can have some fun with that, trying to find out what movies are spoofed.
The movie also offers you an occasional laugh, but nothing that can cause you injuries, thus nothing really funny.
I liked the character IPod in some ways (even though some of the jokes with him are standard comedy 101).
I think this movie (and like most of nonsense/spoof comedy) depends on the mood you are in, so if you think you will laugh to any joke watch this movie. If you are in a serious mood forget about this (re)watch The Airplane instead, it will definitely make you laugh
