This is a great film. It isn't going to be everybody's cup of tea due to its graphic scenes, but it is intelligent and has stood the test of time well. Unfortunately the same cannot be said for this new blu-ray 'remaster'. The picture quality is appalling, with contrast pushed up so high that whites are bleached out and blacks lose all detail. And colours have been changed too, with unnatural greens and the sky almost white rather than blue. Watch the 'Before & After' feature and you can see how natural the colours were BEFORE the restoration. They have completely ruined it. There are quite a lot of good bonus features, particularly the extended interviews, but very little that hasn't been available before. The poor picture quality means that i cannot recommend this disc.
