Mike, I have written so many pages on this forum regarding my appreciation of Hans' scores and musical abilitites that it was superfluous the last time I did it (and the 10 times before that). It is only because I know I am talking to somebody who knows music that I bother again.
Firstly, I have to strongly disagree re. The Gladiator. a, the theme is stolen beyond the accepted levels of musical "borrowing" (obviously it was temp tracked and imposed), so no credit there whatsoever; b) Crowe's personal theme could not have been further from proper musical characterization.
Secondly, I get confused. Has film music become "a parody of itself" like you say - and therefore Hans is the ambassador of that parody, or is he an excellent film scorer? And in my book, an excellent film scorer does not write precicely the same score for three such very different films as Inception, TRON2, and The Dark Knight.
Thirdly, I remember Maurice Jarre recounting how many times David Lean rejected one theme after another after another after another (from such a composer), until finally Lara's Theme materialized. And Jerry Goldsmuth recounting how many times Wise and some executives pushed him into rewrites until he came up with the best fanfare ever in science fiction (Star Trek I). If the artistic standards of those directors had been any lower we would never have had these beautiful film compositions.
Directors/producers these days however are utterly uncultured so their standards of music are as high as the composers' they hire, hence the film music of the last 20-25 years.
As far as sample libraries are concerned, I feel that there is a multitude of articulations available to a proper composer, hence the abundance of great simulations of works by Williams, Debussy, and Stravinsky. However, I do frown upon companies who release (sometimes exclusively!) what I call crutch-patches for the unworthy - you know, completely orchestrated "inspiration" phrases for the uninspirable...
As to what constitutes a composer today, my signature doesn't say it all, but it says it succintly.
Finally, would I empty a whole cart of spiccati and Taikos over a director's head if ordered to score a feature that precise way? For six figures Mike, apologetically, yes. Not before I pleaded to do otherwise though, and more importantly, if asked, I could actually compose the 'other way'; most others would go out of business.
It is one thing to write in 'locomotive' out of aesthetic principles, and a very different thing to do so because you are unable to write any other way...
