Patrick Dempsey (Dr. McDreamy himself) headlines this unapologetically chick-flicky rom-com. He plays Tom, a serial dater who decides one day that he's in love with his best friend, marriage-minded Hannah (Michelle Monaghan). Unfortunately, she chooses that moment to announce that she's engaged to some Scottish chap and wants Tom to act as her maid of honor. He accepts, with the hope that he can break up the wedding before it happens. Original? No. Fun? Maybe, if you've never seen When Harry Met Sally...101 minutes PG-13.
