Lacking the unity of its progenitor (Greetings!), this 1970 film by Brian De Palma and Charles Hirsch stacks the comedic deck both against the audience (too many parodies, too many topics) and against the fine cast (too much improvisation, not enough coherent material for Allen Garfield, Jennifer Salt, and Robert De Niro to work with). The result is a series of potshots: against porno filmmakers, educational television, the black theater of assault on its white audience—against a lot of things in general, but nothing in particular.
