Unpopular opinion: I like PWC more than the BF arc
Fair opinion. BF is loved because we saw Ash bring many of his old pokemon by that point and some great battles, but no old relevant past human character returning (aside Misty).
PWC have some good fan favorite trainers coming back, but a glaring lack of Ash using his old pokemon, who would be perfect to a world tournament. Or just use them in general to present more species to the new fans, instead have Go focus on catching a new pokemon every episode that isn't used at all safe for an arc or two.
Sooooo...
For a series where the characters hang out mostly in Kanto, it was wasted that they didn't use the cast they had there (it was freaking bonkers that Erika, of all Kanto Gym Leaders, appeared).
Galar got the short stick, because of nothing more interesting to offer aside Leon, Raihan and a terribly rushed Macro Cosmos arc. Raihan not be in the Masters 8 at all at the main tournament was dumb. While Allain is nice and all, I'd prefer much more see Raihan defeat Allain than have another charizard appearing.
Also, you basically don't feel attached to any Galar pokemon that aren't the starters or part of Ash's team.
While I came to like Ash's PWC team, it felt strange not see more gen 8 representatives there and at least one more from a past gen that wasn't Kanto or Sinnoh (looking to you, Tyranitar). But, nothing to do about it anymore.
