The commentary!

Deran Sarafian has to be one of the best commentators for a film ever. I thought the cast of Dawn of the Dead was funny, but this guy just rips into every scene. Sometimes they give you a little nugget of information you might not have known, and then this guy goes on about Fulci and getting the zombies to remove their clothing to show off the actors Van Damme like physique, obviously making fun of the other actors.
