The gist I get is that the Denon receivers are *very* good for films,
but, like most others, aren't so hot for music.

I am not familiar with multichannel home cinema systems but I am
curious what this might imply. In what way does the reproduction of
sound for films (which would seem to contain a lot of music) differ
from that for music alone? Is it simply that the pictures distract you
from the poor sound quality and so it matters less?
