You just have to find the good ones. But all in all, the genre has seriously fallen off since the 1970s. Much of the drivel that's shown in theaters these days is hardly worth a look. Regarding a horror film and understanding that horror films aren't usually cinematic works of brilliance (because they are horror films) should do one of three things: scare you, shock you, and gross you out.
That said, there are a lot of people who probably should stay away from the genre all together.
