American Grindhouse

Robert Forster narrates this primer for Grindhouse cinema that features clips with Landis, Fred Olen Ray, Joe Dante, Herschell Gordon Lewis, Larry Cohen, Jack Hill, and many others interspersed with clips from hundreds of movies. It makes the distinction between exploitation and grindhouse, but with a runtime of only 80 minutes some stuff is given very little time and many subgenres like nunsploitation are completely overlooked. I would like to have seen it at a 3 hour runtime.
