Normally I don't review/rate music (I do review products on amazon.de though), because I think music is very much based on personal opinions, emotions and last but not least taste.
Why am I making an exception here? First of all, because the soundtrack could not fit any better to the movie. Not ANY better! Every scene, every emotion in the film is multiplied in its intensity by this beautiful soundtrack. Especially the main theme "The Morrow" has an incredible kind of tragic, melancholic, yet beautiful touch. It gives me goosebumps every time I hear it. Secondly, added, the soundtrack nearly tells a story by itself. Just close your eyes and listen to it. And third part of why I gave it 5 stars is the technical one: the music by itself is brilliantly produced, played and recorded.
Nothing to add. Just listen to it on very good speakers, get a glass of wine first and later close your eyes.
