This is less a documentary than a DVD extra, in terms of brevity and depth of quality. Of course, DVD extras often go "behind the scenes" and this, unfortunately, doesn't. Only half of the short running time specifically addresses the film, its unique characteristics, actor experiences, life on the set, etc. The rest of the time is devoted to repetitive pronouncements on how important and trend-setting the film and its director was, again with little detail, and from a collection of B-grade experts (excepting Geoff Pevere), and maybe 3 people from the film. How nice would it have been to have heard from accomplished members of the film industry having been influenced by this film, including those who did the remake (hey Tom Savini, where are you?), but afraid not. If you're hoping for an insight on the making of the film, its meaning, etc., don't bother.
