Lack of good storyline.

If the ambition is to provide two hours of instantly forgettable, popcorn-munching escapism, it succeeds.

Great movie! If you want to be entertained and have a few good laughs, see this movie. The music is also very good,

The story, direction, characters, and writing/dialogue is akin to taking a tranquilizer shot to the neck, but everything else was so well done.
