See also the trailers for "Predator". Movie is still fantastic, but plays out so much better if you don't know the nature of the predator.
A couple of other movies -- again, no trailers -- which made me feel this way were "Aliens" (they are everywhere!) and "Die Hard" (how is this cop going to beat all these bad guys?).
I don't really feel that way anymore with scifi or action movies, and of course much of it has to do with growing up. But I wonder if teenagers feel that way about the current crop of scifi/action movies, do they feel the thrill, do they feel "the good guys can't possibly win", or is this forever lost in modern cinema, what with all the rushed pacing, spoilers and trailers?
Couple more MCU movies and now I know better how this genre works :).
Because apparently audiences are considered too dumb to put 2 + 2 together. FFS
