The problem with documentaries is the tendency for the movie to just talk at you. (If I want 90 minutes of talking heads, I know where my Stop Making Sense DVD is). This film is fairly ingenious in the ways it avoids doing this. While it is at its core five interviews in a row about a movie, we get a lot of clips of the subjects' own works and the other films they're talking about and it serves to keep the film visually interesting throughout. I could watch this with the sound off. Takashi Miike and Alexandra Heller-Nicholas both came to see it for the first time in very unusual contexts and all of them have good insights on how the film was made and how it hits an audience. It is somewhat telling that all of them focus on the film's visuals, scenery, sets.. but that's what this movie has to offer. Patton Oswalt offers an opinion that The Texas Chainsaw Massacre is the best film title ever. Does what it says on the tin. You're not going to that for deep characterization or a particularly engaging plot.
