This is a well-constructed movie that is entertaining, informative and at times disturbing.
We have seen or heard of all six movies: El Topo, Night of the Living Dead, Pink Flamingos, The Harder They Come, The Rocky Horror Picture Show and Eraserhead. It would be worth an entire movie just to see the clips, but these are presented one at a time, each movie given the full treatment of talking heads and loads of footage.
The interviewees are shown historically and recently. The film moves along quickly, giving a good sense of the film, its production, distribution and the culture it blossomed in.
It's a must-see for any film fan.
