I honestly am not sure what is going on: though I am partially basing this on the anime and media around it as that is part of Pokemon as well. Gen 8 is very much been out of synch: Ash is running around with a Mega Lucario and using Z-Moves after all. I'm not sure how I feel about that...frankly I like Ash doing that but from a marketing perspective that cannot be ideal. Plus they handled Legends Arceus very...unusually, and in a way that seems odd. Like seriously, it sold really well but was barely featured in the anime unlike most main series games (including Let's Go)
Isn't the anime industry in a drought of animators nowadays? Too many animes being done at once and not enough seasoned animators to go around. This and the fact the pokemon generations are becoming shorter and shorter is giving the anime studios much less room to fledge out stories. That and the aimless direction of the series, that certainly doesn't help.
You know it deserves the GOTY.
