Thomas Newman's work for this film...
does make the main impression.
It's not necessary to kill me for these words. Just listen to this very soundtrack yourself.
let me put it like this:
there're several points here:
1) the soundtrack
2) the main personage's performance
3) the plot, which is too much for our dreams, too small for our expectations, and contains in itself an endless story futher to tell for those of us
