Understood. I too have extremely high standards but this is the first time ever that something has come along in the Renaissance/Baroque realm that would work in a mock-up as opposed to only buried as an "interesting" sound in some huge production.
Choir-wise, it sounds like Soundiron's upcoming Mars and Venus choir libraries may be of interest. Only one demo so far (of Mars) but they MIGHT have done a good job of word-building for Old Church Slavonic and Gregorian/Latin contexts. I'm looking forward to it if it lives up to its promise, and can see it possibly mating with the ancient instrument libraries.
By "Hollywood", I quite specifically mean the modern movie productions that are physically based out of there and run by the big companies.
I don't consider Pixar to be Hollywood even though they are popular and widely distributed. They are located practically next door to where I work (SF Bay Area) and have different production values story-wise and musically as well. Same with Francis Ford Coppolla, who sometimes is big but is NOT Hollywood (he too is locally based). What a marvelous self-written soundtrack to "Tetro" last year! Didn't know he was a composer!
I like dynamics and contrast in the music, and story-building and character development. In other words, traditional movie-making values. And thus I contribute to local independent and short films, but put bread on the table with my day job in the audio business (where I cross paths with big names fairly frequently, but fortunately ones that I have respect for :-)), so that I don't have to take music jobs I wouldn't want.
