If the script for this comic spin on Fatal Attraction were only a tenth as hot as Uma Thurman, director Ivan Reitman might have had something here. Instead, he's stuck with one joke stretched so thin it's anorexic. Thurman glams down to play Jenny, a woman whose architect boyfriend (Luke Wilson) has no idea she's a babe superhero until he dumps her. Then she turns avenger who's out to boil more than his rabbit. Sound funny? After ten minutes, it isn't.
