I don't get Horror movies nowadays

I mean, the whole concept is good vs evil, but evil always end up winning which in most cases, that is the true, but it's always the same, the "vanquish" the evil, just so it pops out in the last second of the movie, like a shoddy way to try to make way for a sequel or leaving the feeling that, this isn't over. and they never portrait the good as in another force, it's the human or the victim or the person that is the good, they sacrifice themselves for nothing.
