There's no intellectual challenges made in this movie's plot, and that's how it should be; the characters are only slightly more fleshed-out than any of the ones from the TV show, and that's also not a bad thing - if you put too much seriousness into this kind of film, you wind up killing the roaring-good times to be had. What really makes the film work is the charisma ( & physical charms )of the 3 leading ladies, combined with well-choreographed action sequences and the tongue-in-cheek script. If you enjoy Diaz, Barrymore & Liu ( not to mention Bill Murray )when they're on the screen, you'll love this flick.
