I don't however. I think that, yes, they help disturb the sense of isolation and compassion, but at the same time I welcome the change. Listening too long to this sad music, one is bound to develop clinical depression. That's just a joke, of course, but seriously, this film is one of those rare cases where the composer actually got the chance to develop his themes to their full potential. The vocals that appear in tracks 4 and 8 add to the mood of the score, as are the newsreel tracks.
Cello solos appear evry so often, too.
The score seems to flow effortlessly from one track to another. There are no bad tracks, no sudden outbursts of brass or percussion. This is a fine to relax too if you're in the right mood. All in all, you'd do very well for yourself to find this score. There is some very fine string work on display here.
