Music
Having rewatched this many times I have to say that music is good but completely inappropriate for this film.
Elmer Bernstein was a great composer and I was fortunate to have actually spoken to a few times before he died. His music is great, and has an adventure quality to it. But the rather down ending makes it seem completely out of place.
In fact I saw this movie for the first time when I was about 12 years old. I couldn't believe the British lost. I didn't realize the British were going to lose. The music makes it seem like they're in for a grand adventure, a marvelous spree as one of the officer's says. So maybe the music works in that sense. But I would think this soundtrack would be better for a movie where the good guys win!
I found the soundtrack to Zulu by John Barry to be a bit more appropriate to that film. And at least in that one the good guys win.
