So I'm really late on this, but I just saw the movie.
By strange coincidence, I just barely saw this tonight as well(you're not my kid sister, are you?).
I have to agree. The fight scenes were amazingly hilarious and pretty awesome. It also had some hilarity elsewhere, but much of the rest of the movie was just painfully awkward.
Quixotically, I thought the movies succeeded best when taken as an action film. The fight scenes were far above the quality of those seen in actual action movies.
