Query: A wonderful, beautiful, comical, and unseen gem of cinema

William Peter Blatty made an incredible and unique piece of cinema with this film. This was Blatty's first picture as a director and it's much more personal and accomplished than other directors' first works. Usually first works are good and show great promise, but seeing this you'd think that Blatty must've been directing atleast twenty years before. The story is incredibly personal and thought provoking. I was jaw dropped through quite a bit of the movie, especially at the scene in the bar with Keach and the biker gang, but really all of it. Who knows were Blatty got the story, because it's so unsual and so,completely original because there really is nothing else like this picture. This should be shown more. To me this deserves a better place in cinema and probably DVD. Like Ken Russell's The Devils. See it if you haven't.
