People want the big, expensive movies with big-name actors. How do we know that? Because that's what they pay for. That's the competitive market at work. With modern technology, digital cameras, digital editing, and digital distribution, you can make movies for a fraction of the price of Hollywood blockbusters. There's no barriers to entry stopping you from distributing your low-budget movies to hundreds of millions of people via Youtube, etc. But nobody wants to watch that indie crap. They want $250 million MCU blockbusters. Indeed, you're seeing the push towards higher production values in TV too. Low-budget weekly shows are being replaced by high-budget "prestige TV." Back in the day, "Lost" was expensive (for a new show with an unknown cast) at $3-4 million per episode. Today, Netflix and Amazon are blowing $50-150 million to pre-shoot an entire season of shows like House of Cards, the Crown, Altered Carbon, etc.

And at the end of the day, it's all just entertainment. The market is structured to give people what they want, what's wrong with that?
