Wow, this is one of the cleverest ideas I've seen in a long time. As far as I can tell, they've put together a wide-ranging set of fairly generic-sounding movie music (generic = good, so it doesn't call attention to itself)... but composed it in a way that the three parameters (momentum, depth, power) simply map to different volume levels of the underlying instrumental tracks -- but all perfectly tuned to always prod…
Not trying to pick a fight with you - I agree with your comment overall, but this is a culturally learned thing, very specific to Western movies and TV-series, and it is actually mildly infuriating to me. It is one thing to complement the emotions present in a scene, but being told what to feel is basically a cheap way to try to patch up bad storytelling.
Worse, it can totally backfire: for the dub of Castle in the Sky, the original composer had to fill in a ton of quiet scenes with music because (IIRC) Disney was worried about the audience feeling awkward about not being told what to feel. They also added background chatter, and worst of all: filled in scenes that were quiet on purpose with all of these things. While the orchestral score sounds great in and of itself, in most scenes all that added audio ruined the mood of the original.
However, I can't deny that what you state is what the audience expects, and that it "works", so sadly you're still right.
