How bad is it? Extremely minor comedy.
Should you see it? Only if you're a fan of someone involved.
This was written and produced by Martin Mull, who also stars; Mull's laid-back ironic stance is a difficult one for a film and this doesn't really work. Directed by Robert Downey Sr., there are roles for Dick Shawn, Jennifer Tilly, Robert Downey Jr., June Lockhart, Edy Williams, Mel Welles, Jack Riley, Pat McCormick and Eileen Brennan. The plot's about documentary filmmakers who get to do their dream project as long as they also shoot a porn film. There's few solid jokes; it's more of a continuous mild satire that never catches fire.
