Hollywood should implode and hopefully the art form will resurrect for the better. But for me the primary reason is that they don't live up to what they are supposed to do. Creating good art.
Do I want movies to survive? Sure. But Hollywood as a thing was about vacuuming up every penny it could and that I do not grieve.
I agree that the good stuff is just a result of shotgunning, for every great movie, there are 100 that are forgettable. But we have the habit of concentrating power in one place, so I have no clue how it could be otherwise. Sure youtube is an alternative with myriad of independent creators, but it produced totally different outcomes.
