"Fatal Attraction" meets "Wonder Woman" in this weak effort from veteran director Ivan Reitman. Uma Thurman plays the dual role of Jenny Johnson, Manhattan art curator by day, and G-Girl, crime-fighting superheroine at night, who, unfortunately for her unsuspecting new boyfriend, Matt (Luke Wilson), is super-insecure as well. When Matt makes the mistake of dumping the possessive Jenny, she unleashes the fury of her powers on him. Reitman doesn't know what he wants--comedy, girl-power statement, relationship/date movie--and fails on all fronts as a result.
