If there is less money to be made from big budget movies in the future, then Hollywood will just shrink and make fewer movies. That might sound like a good thing, because you expect them to stop making the same exact stories over and over, but it's going to be the exact opposite at first. The few movies made won't be high quality and innovative. They will be proven formulas that present low risks, which means more explosions, more formulaic romantic comedies and lots more remakes and sequels.
