It's a thrill to watch Posey incorporate, at last, some true emotion into her exuberant screwball wit.

The star's amusingly inventive performance keeps your attention through predictable early scenes when "Ohio" repeats familiar material on women's sexuality. It's like a continuation of "The Vagina Monologues" to see Liza Minnelli, as a New Age orgasm coach.

I'm not really sure how strong this material is on its own: I kept trying to imagine what The Oh in Ohio would have been like with other actors in the leading roles, and I couldn't -- Rudd, DeVito and especially Posey seem integral to it.

Amusing indie comedy blithely blurs the line between risque and raunchy, often to hilarious effect.

A feel-good movie about feeling good, The Oh in Ohio thrums with happy vibes and amiable performances.

A silly, amusing trifle.

Falls disappointing short of its ambition to be both sympathetically straightforward and funny.

This is the slightest and slimmest of sex comedies.

Like the lead characters, who struggle to get "almost there" and fail, the movie provides a good time but isn't wholly satisfying in the end.

First-time feature director Billy Kent seems proud that his movie deals with sex in such frank fashion. But if you're going to brag about your explicit sexuality, it doesn't quite work to go out of your way avoiding skin.

Posey and Rudd are the real deal, so it's almost sad when Priscilla and Jack are left hanging in the final act, their issues unresolved. It's as if the filmmakers lost their nerve when it came time to write the kind of intimate, revealing conversation that can make a sex toy unnecessary.

Even Posey -- who brightens most movies she's in -- fails to stir the movie's unresponsive tectonic plates.

Posey is as over-the-top as a drunk in a game of charades, while DeVito wears the sunny, slavering grin of an old coot hoping to get lucky at Jack Nicholson's pool party. If it still sounds like fun, good luck. Don't blame me if you leave frustrated.

One of those movies that promises much but doesn't deliver. Despite a lot of misplaced talent, this movie is as silly and forced as its title.
