It's because that's how things work with public viewers, to attract more viewers they make gimmicks that are so simple in nature it doesn't need too much brain activity to understand (since it is a fact that majority of the world's population isn't intelligent), and often has content that is a bit "sexual" or "violent" in nature. But the downside to that is, it doesn't become a work that is worth to be remembered in history, since it's not an artwork, its sole-purpose is just to attract viewers, not to challenge them and be remembered throughout history for making a difference. Just my 2 cents.
