I must admit I'm not a huge Sound of Music fan, but my wife and children absolutely love it. She got this as a Christmas present and despite having watched it quite a few times on DVD, they couldn't believe quite how much extra the bluray added to the experience.
There is very little to be said about the film - a great feel-good love triumphs all romp, with the Nazis as the bad guys and Maria's angst between her calling as a nun and her love for the Von Trapp children and their father. One of the best loved and most watched films ever.
Picture Quality - this is right up there with anything else that bluray can offer. The scenery is stunning, the colours are vibrant, you can almost smell the alpine air! One part of the film centres on Maria wearing a dowdy dress - that even the poor people didn't want. We really appreciated that much more because of the detail shown up in High Definition. The film is presented in 2.20:1 format, so you still get some black bars at the top and bottom of the screen, but that is how it should be, and certainly didn't detract from the experience for us.
Audio Quality - well a film about music, with such a well recognised sound track, absolutely has to get the sound right - and it does. Again there were things audible here that never were on DVD, watch out particularly for the nuns singing in the Abbey. The dialogue is a big issue for me. I don't like muffled speech and having to change the volume, but there were no worries here because we didn't have to. The top track is a 7:1 DTS soundtrack that has really treated the source material with respect.
Extras - This film comes with a feast of extras, as befits its iconic status. We haven't looked at all of them - in fact it would take quite a while to do them justice, but the ones we have looked at were all very well done and very well presented. You could quite easily lose yourself for several hours here.
So in summary a very easy decision - no doubt at all that it deserves 5 stars.
