Bullshit! I don't have to watch two or more people having sex together to know about the problems of sex. I don't have to listen to commedians using the F word whenever it suits him to know about ghetto problems. I don't have to watch one person cutting off another person's fingers to know about drug deals. Hollywood puts all these things in movies purely for profic, just for the $$$.
What you are describing are extremely insipid movies that are being juiced up with bits of sex, cursing and violence, for profit motives. That is exactly what I call Hollywood's wishy-washy attitude. It's easier for them to find a stupid boring script with no meaningful themes addressed in any meaningful or interesting way, and then juice it up. My point is, the problem is not so much the sex, cursing and violence, because these things are just the by-product of a complete lack of imagination, creativity, and critical thinking from the Hollywood crowd. And it is that which I am more afraid of, because it is a lot more dangerous to go on about your life with too few sources (of inspiration) that challenge you and develop your critical thinking, than it is to "be scarred for life" (sarcastic) by a few explicit scenes or some bad language.
Notice also that there are examples at the other end too. Take, for example, the Hollywood version of "The Girl with the Dragon Tattoo". They took a book that involved very peculiar and interesting characters, yet very real and believable, that shatter a lot of the standard molds, and which are involved in a rather non-linear story-line. With that, they did exactly what I would expect Hollywood to do. They transformed the characters into standard Hollywood-mold, pre-fabricated characters (e.g., the standard male hero character you find in any thriller, and the standard shy "damaged" girl, scarred by a bad childhood. Which are both at polar opposites of the corresponding characters in the book), and re-fitted the story-line into a standard Hollywood 4-act thriller. Now, the product is a reasonably entertaining Hollywood thriller, like all so many others, but with nothing special or interesting about it. Which is a real shame, because the books are pretty subversive of the standard molds, and challenge your pre-conceived ideas a lot, but that's not acceptable for a Hollywood movie, it doesn't fit the recipe, so they had to water everything down.
The thing is, Hollywood caters to its audience. Some decades ago, people wanted wishy-washy boring movies without any violence, cursing or sex. Now, people want wishy-washy boring movies with bits of "cool" violence, cursing and sex. And you find older people essentially complaining about not being the target audience anymore... well, tough luck.
The problem is Hollywood always playing things super-safe, peddling pre-conceived ideas, recycling the same character arcs all the time, playing to standard molds, and so on. They are selling one product, with one stream-lined recipe. That's the problem. And as far as I know, it has pretty much been that way for at least 50 years. Some ingredients in the recipe change a little bit over time, but that's inconsequential, just catering to the evolving tastes of their audiences. Once in a while (every couple of years or so), good movies slip through and become more memorable than others, so every decade has its hand-ful of memorable movies, but most of what comes out of Hollywood is dog-chow for the brain, and has pretty much always been. You can complain all you want about the latest flavor (which I agree is a bit more "spicy"), but at the end of the day, it doesn't matter much.
