I think that the people in the filmmakers' chairs have become less musically refined (a whole generation of directors from the MTV crap school of directing so they want the lowest common denominator of musician who is a "yes" man who has more books from Tony Robbins than Adler, Piston, and such in his/her library.
I hate what film scoring has largely turned into these days. It sounds like utter noise or vacuous sound FX. Technology sadly has not helped. Anyone with $$$ that can afford VSL or Symphobia can sound good. At least with VSL, you still need music chops to get the full effect- I love Project SAM and all but Symphobia is partly to blame- having the ability to play sounds that were programmed and sampled by composers who know what doubling works and what instruments work in a given register is kind of cheating. For me, I have created Symphobia-styled multis for sketching using VI Pro and I love it because I know how to separate each section when it comes down to fleshing out the music. I doubt 50% of those who use Symphobia could do the same.
I also think that playing things into a DAW in realtime largely is very idiomatic and not very musical. It depends on a person's piano skills and let's be honest, most people who use DAWs (professional and amateur) don't have concert like pianistic skills. Some do but most don't. They fix their performances with a lot of editing. I much rather input notes into Sibelius and look at the contour of the line, or density of a specific passage for orchestration purposes. I have a harder time doing this with Logic or DP. I also find my music is more static when performed into a DAW. There's less meter changes, less changes in tempi, more constant articulations (i almost have ADD when I'm scoring in Sibelius where I like to change textures and instrumentation quite often- I blame studying Mahler's Das Leid on that though).
Anyhow, there are still a few gents that know how to write themes. Alexandre Desplat is probably one of the bigger name composers who does. Gabriel Yared, Chris Gordon, people like that.
