This was not intended to be about David Berkowitz. It's about one man's obsession with the case and the convoluted story he told. You can certainly believe it's all bunk and that the Satanic cult panic of the era drive him. That's the point. It's about his obsession. It's up to you to listen to the evidence and make up your mind. I would agree it's way too long. It's compelling stuff, though. Too bad people set their expectations on something that was clearly not the intention of the filmmakers.
