Well, I had to wait 10-11 years but it is rewarding to see Daryl allowing himself to temporarily stray from his British cool and tell it like it is. My! Underscores must really be getting even more vapid than before - if that is possible - to get that kind of "rise" out of him...
JimmyHellfire elaborated upon what I said articulately, entertainingly, and Icecubeman punctuated it. I am going to add a couple more things, only because Muzicsculp is not alone in his misconception (which in my opinion drew DG's indignation), but is a member of a prodigious population of Platonic cave-dwellers (no offense intended).
Firstly, film music (the early, great film music), spun out of concert music as an offshoot from one of its branches (programmatic music), and developed in tandem with the rest of the tree. It is not its continuation.
Secondly, most - if not all of film orchestrations derive from concert music (past and present), and only a small part of it at that. Even the electronic inclusions derive from the tiniest of regions of the serious electronic music universe. And why shouldn't they? It's only film music; it's not Mozart.
However, one does not encounter much modern concert or electronic music (real EM, not dance inspired) outside of tertiary education, so it is understandable that most people of good intentions can arrive to such uninformed conclusions such as Muzicsculp's, frustrating for some of us. The same goes for musicianship, harmony, polyphony, form, range, variety, taste, ......
Such a pity, if only all those people knew how much could be added to their pallettes through some serious inquiry into serious music. Alas, this is much harder than mastering a DAW and copy-paste skills and, as it happens, seemingly unnecessary in today's film/video/TV worlds...
