An anti-establishment comedy, Greetings is the sort of film only the late '60s could produce. And while it superficially has little in common with Brian De Palma's better-known later work, viewers familiar with the director will find a fair share of connecting points, including a voyeuristic young film enthusiast played by Robert De Niro. Any film broken into loosely connected vignettes almost invariably suffers from unevenness, and Greetings proves no exception. For the most part, though, De Palma does an excellent job of sustaining interest. Enthusiastically incorporating -- too much so at times -- techniques from the French New Wave, he creates a richly detailed picture of counterculture males pursuing Kennedy assassination conspiracies, trying out computer dating services, and making films for the basest of reasons (in a scene as film-savvy as any De Palma has ever shot), all the while living in the shadow of the draft. A fascinating and often funny portrait of its time, Greetings should prove interesting even to non-De Palma diehards. Just beware the more experimental moments of the soundtrack by the Children of Paradise.
