Seeing Other People is a triumph for writer/director Wallace Wolodarsky, not only on its own terms, but also as a leap forward from his most recent stint in the director's chair, the infantile comedy Sorority Boys. From its cast to its dialogue to its intelligent framing and editing, Seeing Other People is a Sundance natural, a near prototype of the indie relationship dramedy. Its premise is a little too fraught with peril for a normal couple like Ed and Alice, but Jay Mohr and Julianne Nicholson sell it with earnest performances. A good-guy role is a refreshing change for Mohr, who's usually asked to play the smarmy fast talker. His well-meaning character gets twisted around by the unnatural requirements of a no-win situation. He's damned if he watches his fiancée have all the fun, which feeds his jealousy, but also if he adds more notches to his bedpost, which feeds hers, not to mention widening the experience gap between them. Nicholson, on the other hand, is in it for this kind of conquest-oriented numbers game, but discovers herself forming a second monogamous relationship that illustrates the failings of her first. As the roles flip-flop and numerous side characters get entangled in their experiment, Wolodarsky examines the notion of fidelity from every angle, with rich results. He's even got time for the parallel story of a romance sputtering to life between Ed's friend (Andy Richter) and a single mother (Helen Slater). It's comparatively dull, having slipped almost immediately into the comfortable, cereal-eating boredom of a stale marriage. But Wolodarsky implies that this may be as functional as relationships get, in a world where people judge their ideas of love and sex by the unattainable standards of movies and television.
