It seems the criterion for being asked to participate in this documentary was "does Ed Wood still owe you money?" All of Ed's associates are there bashing him and cashing in at the same time. Good for them. Ed was a dishonest guy and he owes them all one at least.
The story is fascinating of those who were stepped upon by a man who pretended to be a Hollywood director/producer/writer. He was so good at pretending though he actually finished a couple of films.
It didn't matter that he had no business doing it. This is the story of how Hollywood could be hijacked for a short time, when it wasn't looking. For this feat Ed Wood is still admired by fans of truly independent film. Wood cheated Hollywood, investors, studios, and even his friends, but he never cheated his audience. Ed Wood did what he wanted to do. He made the films he wanted to see. It's just that his tastes weren't all that refined. Fortunately, neither were those of the syndicate stations who played Ed's Plan 9 from Outer Space ad nauseum in the 70's and made Ed a cult legend.
The biggest problem with The Haunted World of Ed Wood is the fact that actor/mystic seer "Criswell" is given short shrift.
