The ratio is actually about 98% real movie with 2% porno spliced in. The porn parts are also not... 'fun' in the way pornhub would be. More disturbing than sexy. What's interesting about it is the novelty factor. It's essentially a big budget film with Malcolm McDowell, but it feels like a "B" movie. It does manage to capture this certain mood/tone of complete and utter insanity. It's pure hedonism and madness with this ever-present sense of dread and anxiety. It's not a good movie, but it's definitely unique.
