The film starts on a premise; the premise of Jack Jericho (Robert Downey Jr.) being able to pick up any woman he wants (which works, considering his smile and the way he talks). There is one woman who piques his fancy, but she doesn't want him.
Set over 48 hours, the films bucks through twists and turns, including seeing a side of Jericho that was unthought of with the wya he treats women (he is a teacher who lives with his ill grnadmother). It is this human side that allows us to not hate him so much for being successful at being a git.
But the film cannot be saved by him alone. With a weak storyline, and a typical happy ending, the film does not answer all the questions, but is suitable froth for a chick flick
