The “Evil Dead” franchise has seen so many home video releases, that between commentaries, making-of featurettes, and interviews, that it has amassed more special features than Stefon’s latest nightclub find.  While Anchor Bay drowned us in “limited” editions of each film in the original trilogy, one person was barely accounted for: special effects artist Tom Sullivan.  Sullivan’s story is told with humor and heart in the latest Synapse blu-ray of director Ryan Meade’s “Invaluable: The True Story of an Epic Artist.”
