Funny, that was already true in 2006. It's the thing people keep saying, and yet anime keeps coming out.
Right now they're stuck in the whole "ten shows from the same budget, each run by their own 'committee' and each competing for cash that runs out well before the show's over, and the poor performance very quickly get less per episode". Great for networks, shit for shows. Even worse for animators who need to get paid a living wage.
A cursory glance of anime tv shows released in 2006 and there's a lot of good things I'd watch again: Honey & Clover, Kemonozume, Ergo Proxy, Code Geass, Haruhi Suzumiya, etc.
In 2026 the only thing that has captivated me, so far, was the Chainsaw Man movie and Dorohedoro S2.
