The problem is, people don't watch horror movies the way they do other movies. Horror movies have become the go-to place to go when you and your buddies are all wasted and silly. The audiences I've been in for most horror films recently have been so unruly that it completely breaks immersion. They expect horror to be campy and so-bad-it's-good, and they love cracking up over one of their bros flinching like a 'little bitch' at the jump scares. It's a good time for them, and the movie certainly doesn't have to be good to get their ticket money. Then you have the people who use scary movies as a backdrop to cozy up to their date, which usually ends in them making out through half the movie. The movie certainly doesn't have to be good for something like that.
