Yes, Turning Red and Luca are vastly superior animation to Mario. This isn’t even debatable, it’s the entire point of Illuminations existence. It’s why Universal owns both Dreamworks and Illuminations - there is a clear distinction in quality.
As for “they’ll just write original scripts,” it’s a claim so divorced from reality as to be laughable. It reflects a complete ignorance of the way modern entertainment companies are organized, of the realities of marketing in a global market, of just about everything about the studios. The studios didn’t just choose to focus on IP- it was a necessary reaction to a series of interlocking structural changes. Look at the box office over the last decade - films without IPs don’t sell. Films based on NEW IPs rarely sell.
And by the way, you’re expecting this shift to be inspired by a year in which the huge hits were based on massively popular IPs and family films without IPs, usually a fairly safe bet, proved to be major failures. It’s a fantasy.
But then a lot of this thread is engaged in fantasy, pretending that adversity will make studios MORE adventurous or that whoever comes after Iger won’t almost certainly be worse. It’s pure wishing.
