What a disappointment . I don't understand all the raves for this CD, I was so disappointed when I listened to it. I've always liked John Barry's film scores but in this re-recording all life has been drained out of the music. Where's all the emotion, the excitement and pathos? Instead, every track sounds the same -- they're all filled with a melancholic boredom. Give me any of the original soundtracks over this "easy-listening" interpretation
Output:
NEG
