I think this is ignoring the seas of dross that have fallen away in the past. There have always been bad movies, and unoriginal movies, some of them doing quite well at the box office(used as a metric to show that people were showing up to see them). We don’t hold a lot of them in popular memory because we don’t watch them anymore, and what’s left from those eras are the movies of sufficient quality or resonance that we continue to watch them.

The system has a number of issues that are well trod, and certain pitfalls which are inherent, but hanging a lack of quality or unoriginality entirely on capitalism is overselling it.

I would posit that a lack of moderation, or a form of monomania is a bigger culprit here. Too much focus on the business side can stifle creativity, but too much focus on the creative side can result in sprawling, unfinished messes. With too much focus on safety we can be stigmatised from action, but with too much focus on action we can lose our humanity in favor of feeding the gears of progress.

This accounts for the bean counters, but doesn’t grant them the power of being the one true reason for everything being bad.
