I don't really care about modern horror, but I have long tried to get people to understand those same points about studios. They care about cash, not quality. In TV, it's ratings cheaply earned. Thus, we're punished with the persistence of "reality" TV. The government itself couldn't have produced a more insidiously ironic label. In movies, a successful product brings in at least 3x its budget. You might get a sequel approved with a lesser performance, but at 3x its practically guaranteed something will be in the works no matter how toxic the film might be.
I know there's no set formula to assure a hit, and I know studios do apply pressure to directors who seem overly concerned with art rather than filling the coffers, but sometimes I'm still surprised when those individuals get as much latitude as they do.
