It really isn't. A trailer is designed to lure you in, usually pulling a couple of the best shots from the movie or a few great lines that will stick with you. There will always be the occasional bad trailer for a great movie (Pixar in particular seems to have trouble with dull trailers for superb films). But at the very least, a trailer should be able to put its best VISUAL foot forward. If people only went to the movies for the "plot and characters", Expendables would have made pennies at the box office, Fast and the Furious would not be counting up to part 6 and 7, the slasher era would have ended with Scream, and we wouldn't have annoying ads on this site reminding us that DieHard 5 is a great alternative to boring traditional Valentine's Day festivities.
Just as people will always go see movies for the explosions, people will just as easily avoid movies for certain reasons (like cringeworthy CGI). And that is OKAY. It isn't "pedantic" or "shallow". It's just personal preference.
