Breaking up is hard to do but when your superhero girlfriend can shoot lasers from her eyes, it's even harder. That's the premise of this amusing high-concept comedy starring Uma Thurman and Luke Wilson. It boasts at least some of the good-natured mischief and mayhem of Ghost Busters, which put Ivan Reitman on the A-list of Hollywood directors in the 1980s. With his hangdog handsomeness and tendency for self-effacing humour, Wilson is perfect as the boyfriend who is slowly emasculated by atomic-fuelled scorn. Thurman is also convincing as G-Girl, but it's a shame that in the second half of the movie, Don Payne's script abandons all sympathy for her. She morphs into a gross caricature of Glenn Close's seminal bunny-boiler from Fatal Attraction and though that's the crux of the joke, the gags do start to wear a tad thin. Ironically, it's the weedy ex-boyfriend who carries the weight of this saga.
