My Super Ex-Girlfriend manages to do what the recent crop of crime fighters haven't: show us how much fun it might be to fly, or have super strength, or look buff in spandex.

Casting helps the film work. Uma Thurman is among the few actresses who can pull off this role: the hot, buff, slightly deranged superhero and her dowdy, un-sexy alter-ego.

A one-joke movie if ever there was, but the joke happens to be a good one -- a Tracy-and-Hepburn-style battle of the sexes in which Kate can fly and blast through walls -- and director Ivan Reitman (who made Ghostbusters) feels at home with the mix of screwball and supernatural.

The two starring performances are spot on. Wilson gets the tone that screenwriter Don Payne so expertly evokes: It's a weird sort of self-aware despicability...Thurman is beautiful, fearless and perfectly believable as a superhero.

The movie doesn't purport to have her stand for all women, just the crazy ones, and as such, G-Girl is pure, soul-cleansing id catharsis.
