Also, not a movie but a TV series, Battlestar Galactica (the new one). Bear McCreary created a space opera (the shape of things to come, Prelude to war…)

It has to do with modern very-flexible digital editing (don’t want to lock in a Final Cut early enough to allow for production of a quality score timed to the edit) and editors/directors extensively using placeholder music, editing to that exactly, then just asking for a clone of whatever lame tune that was, as I understand it. Basically, having a shitty soundtrack just lets them get done with post-production faster, and keeps them more flexible until closer to release

Middling 90s movies like Twister and The Ghost and the Darkness punch way above their weight thanks to the soundtrack. You almost never see that any more.
