Sure, two things.
First, as
@muk correctly said, it takes some skill to produce this sort of thing so even if you don't like the end result, you can appreciate the production and mix. Something to keep in mind with ANY genre of music you don't like.... I always focus on the production and mix when I listen to radio pop
Second, there is room to appreciate these pieces artistically once it's understood that the form is DELIBERATELY strict and narrow.
Late classical and Romantic music is all about constructing forms so huge that eventually form itself becomes invisible. These trailer pieces are like a return to the mentality where a piece of music is of X genre and therefore has some strict form Y which unfolds within a few minutes.
This was something Baroque composers were very well-versed with (courante, allemande, concerto, etc). They understood and expected that a listener would recognize within the first few notes that a particular piece is a sarabande, and then they would follow along with the form of a sarabande in their head as they listened to the music.
Strict, foregrounded form doesn't mean the composer lacks imagination or they are just "following a formula."
Think about a building you've been in where the architectural elements are deliberately exposed, perhaps a convention center or airport terminal:
This isn't ugly or stupid, right? It's not like the architect "forgot" to put drywall on all these exposed steel beams.
So, these pieces are taking place within a form of repeated chord progressions - with very few in-genre options, by the way, for doing anything besides major or minor chords. For instance add9s, add6s and maj7s are permitted, but only on certain chords. And naturally, the chord progression has to cycle back to its own beginning, so not only is there not any modulation, but the start chord (almost always
i or
bVI) and end chord (usually
bVI,
bVII, or
V) have very few options. And as a final restriction, you have to get from start to finish within 4 or 8 measures.
The goal is, within that very narrow language, how do you keep the listener's interest, and keep a sense of momentum going. Often it relies on a "third act twist" where some countermelody is added, or the harmony is shifted (
i is substituted by
bVI for instance). So that not only does the music go up a notch in intensity for the third act, but it also feels as if something revelatory is happening.
All of this is not new in film music by the way. Film composers have always had a good reason for experimenting with this form. It puts less demand on the listener. Music that is super developmental and nimble and modulatory naturally
foregrounds itself, it demands attention. Music that cycles can stay in the background.
Some examples of how this musical form is NOT just "one note johnnies" smashing their MIDI keyboards:
