Thanks for that, I would disagree and say that Week-End certainly does fulfill on all counts!
It was only after viewing the film a second time a couple of years ago (the first as a far less discerning teenager), that I came to realise exactly how scarily dense the film is. Each 10 minute reel is its own take on a little hell, in an incomparable way to the last. From the opening rhyparography, which is quite the most interminably filthy monologue ever committed to film (expatiated descriptions of rimming in 1967??? That is f-ed up enough in itself), through to the non-sequitur survivalist/cannibalist/conservationist surrealism of the finale, the whole thing feels like a weekend-long horrible nightmare. It really isn't an easy viewing experience, and is even harder to shrug off some time afterwarRAB, when you begin to recall it in your consciousness.
