If proof were ever needed that Robert Altman and teen sex comedies are an oil and water mix, O.C. and Stiggs provides it in abundance. Clearly slumming in the hopes of getting a commercial hit that would allow him to make more of his idiosyncratic, often brilliant, personal pictures, Altman just as clearly seems asleep at the wheel here. Although the director makes a few half-hearted attempts to inject something of interest into the proceedings (such as references to other movies, including The Wizard of Oz and his own Nashville), there's little of distinction. This actually is probably to the good, as any serious attempts to make O.C. into anything resembling a "real" movie would probably result in a disaster. As it is, O.C. is mostly dull, with very little that is actually funny (let alone witty), and with two leading characters that, even for the genre, are sophomoric and unappealing. Of the principle cast, only Ray Walston, struggling mightily, rises above the material and somehow provides genuine entertainment. The dozens of familiar faces that flit through the film give it a momentary bounce, but mostly of the "Look, isn't that Tina Louise?" variety. There have been worse Altman films than O.C., but this one stands as the most unnecessary of his career.
