I fully agree with you. I too find 'Omaha Beach' as emotional, if not more so than 'Hymn to the Fallen', definitely a sombre highlight from Williams. The only track that doesn't have much emotion is 'Wade's Death', but even that is listenable.
As for the main theme, it appears several times throughout the score, and how the first review does not identify it is beyond me - I find it very hummable.
Sorry Christian, but this score deserves 3 stars at the very least.
