I won't be watching the new series and it has nothing to do with my being an Ash fan. I am one of the original fans and watched almost every episode until the end of DP. BW started off nicely but quickly turned to sh*t and that was the time when I stopped watching the Anime. Just checked on it once a week through Serebii's homepage. And the same thing happened with XY, SM and PM(2019). Lockdown gave me the chance to watch XY and it was great. PM(2019) had lots of issues but this is not the time to list them.
Over the years I have watched them butcher characters after characters. The new ones might be different but I can't relate to them. I tried watching Ms. Marvel and while it was a nice series, as a guy in his 30s, I had a hard time relating to the teenage love triangle stuff. It's the same with Pokemon. I would rather invest my time somewhere else than watch the story of two 10-year-olds.
It is not like I have stopped caring about Pokemon. These days I focus more on competitive battling. VGC is fun and it is more exciting, for me, than the repetitive Anime. There's not much that can be done with the Anime. It has to follow this same formula even if the goals are different. Most of the episodes are fillers and we can't have Kanto(OS) like fillers anymore. In the 90s people didn't know much about Japanese culture and Kanto gave us just that. After Kanto the Anime became less Japanese and more global. Quality suffered and people started hating the fillers. On top of that, with later seasons, they became more marketing-oriented.
So yeah, I won't be watching the new Anime but good luck to all who will.
