Well, when I first started listening to trailer music was when it first started getting leaked. That was when I was first entering video production as well. So, I watched, and participated in, a lot of video productions (say just gameplay videos) that would then all rely very heavily on this music. I wouldn't say it's necessarily bad on its own, if you consider it independently of this fact, but the leaks became more prominent and the usage exploded. Soon it was very hard to find such media without them all using the exact same music, and I ended up becoming very opposed to it (making too much use of a good thing, so to say).
I can understand why it's overused, especially having watched a lot of video productions come to rely on it, and in turn a lot of mods (I was making the same argument against the massive over use of final fantasy soundtracks back before this), and to me it feels to greatly diminish the impact of the individual pieces when they are heard so much elsewhere. This is more a problem with TSFH, IM, and X-ray dog - some of the companies less-known produce equally good or close to as good work and aren't nearly as widespread, but I end up looking for alternate sources for my projects anyways out of style considerations. After all, I can find plenty of emotion and epic outside of this even if I wanted a similar sound.
I also understand why people don't feel anywhere near the need to devote time to building such tuned soundtracks as I do. In a way, my experience has been ruined I suppose. But all I have in life is time to make ends meet, and so time is indeed burned in gratuitous quantities. Unfortunately, I was not up to the task of composition myself. Being completely and utterly incompetent, I failed to make anything I could myself respect.
