Review in a Hurry: Goofy cuties Cameron Diaz and Ashton Kutcher are equally matched in a rom-com nicely suited to their sparkly eyed qualities. What Happens In Vegas is about as silly and pleasant as it needs to be, no more, no less.
Back home, an irascible judge (Dennis Miller) sentences the couple to "six months hard marriage" (ouch!) before they can collect the fortune. Well, that won't happen without a fight—or two, or three, or, like, a hundred.
Both Diaz, with her gangly charm, and Kutcher, the lovable doofus, fit perfectly into this breezy, occasionally tasteless, mostly enjoyable comedy. Vegas knows better than to try to be serious or meaningful or, God forbid, anything else that would cause both leads to emote any more than necessary. And no matter how much they fight, Joy and Jack's antics stop just short of viciousness, keeping the audience with them.
As the inevitable best friends, Lake Bell and Rob Corddry fill their duties brilliantly. While Diaz and Kutcher are griping and fighting, these two are given the best one-liners (and it's obvious that Corddry cooked up some of his own). It's doubtful the movie would be nearly as enjoyable without their presence.
The 180—a Second Opinion: Sure, it isn't meant to be brain surgery, but Vegas robotically hits the usual rom-com marks without any attempt to try something different. This unimaginative storytelling might lull you to sleep if the two hot leads' charisma isn't enough to prop up your eyelids.
