Firstly, let me just say - I find it particularly odd that both the other reviewers of this product complain about the additional footage to the Redux version of the film. Surely the main attraction of this disc is that is contains both the Redux and the 1979 theatrical cut.
The transfer and soundtrack of this BluRay disc is great - it's definitely the best the film has ever looked and sounded. And having both versions of the film on one disc is good too. Some people prefer the original, some the extended version. Me, I'm undecided. I can see positives in both cuts.
However, the main reason this disc is only scoring three stars instead of five is a complete and utter lack of bonus features. The DVD had a wealth of extra material, not least the brilliant Heart Of Darkness documentary. Not to include this on the BluRay - even in standard definition, seems plain bizarre. Nothing else either, no trailers, interviews, outtakes etc. All we get in a commentary track, which to be honest very rarely appeal to me.
So that's it really, great films, great video and sound quality, pretty crummy disc.
