I think good art comes from individuals with fantastic visions; but since no individual can fund things at the scale to compete in the attentional arms race, we are left with endless bland re-hashes since these compete on existing brands and thus are lower risk.
There are probably more than 10x as many people who remember liking the lotr movies as a kid than who are close enough friends with a member of that fanatical core of Tolkien fans to have the show personally recommended to them and probably many times again as many people who are just generally aware of the popularity of LotR. That's the real benefit of the IP. Having some really dedicated fans help hype it up for a few weeks/months before it comes out doesn't hurt, but their job is pretty much done by the time it actually releases.
Today I saw physical adverts for House of the Dragon on the train ride home. The only thing I thought about was how shit the last season of Game of Thrones was and how I will never read any media about that world again. Even though I would have watched a new show set in a completely different world with the production quality I saw in the posters.
Currently Big Corp is spending billions on acquiring IPs which rather quickly end up having negative value. This is, to put it mildly, not good business sense.
