I used to have a different issue with movie trailers, which was that every other one was narrated by Don LaFontaine with that breathy, ominous voice ("in a world...). I had nothing against the man personally, and I'm sorry he died, but I do not miss that voice one bit.
Now, I have a new issue: the quick fade-outs and fade-ins between tiny snippets of action "thrills," the speed of which escalate until they really give me a headache -- they become almost strobe-like. If you are in a theater sitting through six trailers and three of them use this fade crap, it's sensory overload, especially when every tiny cut is accompanied by its own musical "stab" or a "whoosh" or whatever is on those DTS tracks, forced on us at volume levels that way-y-y exceed reference..
I thought this technique was interesting when it was first used, as an alternative to regular direct cuts, but it grew old really fast, and it seems like every other movie trailer now employs it (at least, the action trailers do). Monkey see, monkey do!
Enough already, Hollywood! I know you've lost almost any interest in being original, but how about not having your trailer companies turn out these carbon-copy train-wreck trailers, and encourage them to spend their time creating the kind of wonderful mini-movies (sans spoilers) that you used to.
