Remember when romantic comedies used to charm and surprise? Of late, the entire genre seems rote and predictable. The latest addition to the list of uninspired rom-coms is this busy tale of two New Yorkers (Diaz and Kutcher) who meet, party hard and wed in a night while vacationing in Las Vegas. Upon sobering up, they plan a quickie divorce—but a pro-marriage judge orders them to cohabit for six months if either wants to see any of the $3 million they won together at a slot machine. Want to bet that dislike will turn into true love? Diaz and Kutcher each trot out their usual bag of tricks: She flails her arms and acts goofy, he sputters and tosses his hair. No viva Vegas here.
