"It's Complicated" has the makings of your typical silver screen love triangle except this time the players have droopy eyelids, urinary incontinence, and listen to self-help CDs on rebounding from divorce.

Writer/director Nancy Meyers cleverly turns the phrase, "its complicated," now infamous as an ambiguous relationship status on Facebook, on its head in her latest film - proving that undefined relationships, drunken sexual romps, and sneaking joints in the bathroom aren't just for the kids.

Jane (Meryl Streep) is a happy, albeit celibate, divorcee with the requisite movie land dream job as a bakery owner, gossipy gaggle of girlfriends, and fantastic house that she's making even more fantastic with the help of a mild-mannered architect named Adam (Steve Martin).

Despite his irritating new wife Agness (Lake Bell), Jane has a placid, if not friendly relationship with Jake (Alec Baldwin), her ex-husband and the father of her three children.

It gets a whole lot friendlier, however, when after a wine fueled night of reminiscing in the hotel bar before their son's college graduation, Jake and Jane find themselves in bed together.

Despite some reluctance on Jane's part, the reignited flame proves difficult to extinguish and they are soon entangled in a full-on affair.  

Jane struggles to navigate the murky waters of becoming the other woman - should she feel guilty about wronging the woman who once wronged her or is this simply the ultimate form of karmic retribution?  Things get even trickier when Adam starts expressing interest in more than just Jane's architectural plans.

It would be hard to assemble a cast more deserving of the title all-star - Steep, Baldwin, and Martin all live up to their well earned reputations and show off some impressive comic chops.  

Baldwin and Streep have excellent chemistry. Steep's Jane directs some perfectly timed eye-rolls Jake's way, and you get the sense that she knows better even though she can't stop herself.

Baldwin seems to be completely devoid of guilt over the fact that he is potentially ruining yet another marriage, but its hard to hold it against him when he busts out with one-liners like "O-M-G, I thought he'd never leave," after he hides in the bushes awaiting the departure of Peter from Jane's house.

Martin nails his character's dorky charm. His stable, loyal, and down-to-earth Peter serves as foil to Baldwins's goofy, gregarious, immature Jake.  

"The Office's" John Krasinski also stands out as the hilariously jolly fiancé of Jane and Jake's daughter who is not above wearing his betrothed's pink pajamas or joining in a group hug with his future in-laws.

Despite these stellar performances, the predictability that so often plagues this genre rears its ugly head.  Coming off the heels of giddy hotel room tryst, Jane plans a romantic night for Jake. She dresses up and prepares his favorite meal complete with wine, candles - the whole nine yards. Shock of shockers - he doesn't show up and her hard work goes to waste.

Still, "It's Complicated" is easy to watch - the characters are likable and even though they lead the sort of shiny, perfect lives only found in the movies, you find yourself rooting for their happiness.  Its certainly good for a chuckle and while it may not be groundbreaking, this is after all a commercial romantic comedy, it is refreshing to see a film driven by older characters that's light, fun, and sexy. The Golden Girls would be proud.
