This is a terrific review of the horror genre in films. Lance Henrickson narrates. John Carpenter and numerous other exceptional horror film directors reflect on this from the silent film era to date (2009). They leave out a few films like "Terminator" (1984) and "A Clockwork Orange" (1971), however they really go in depth to the socio-economic-pathologic aspects of so many films. A must see documentary.
