- Ash owning a Lucario honestly doesn't bother me that much in theory because it's exposure has been way less obnoxious than Eevee or Charizard's and now Dragonite's at this point
- Goh is just there. I don't have a huge amount of feelings towards him but his overall hatred that he gets at times is just.. why? I also don't care about his legendaries most likely because it's not like he's using them in a competitive manner anyway also SM kinda already broke this mold
- This has already kinda been said A LOT but I wanted to add more talking points and plus this is an overall opinion, Iris becoming Champion isn't glaring nor that weird. A character's development does not stop when they stop following Ash. If you could believe Ash could go from BW Ash to Champion then same applies here.
Truthfully several of Journeys' ideas are things I really feel could have done with better execution, but I can at least see what they were going for.
Goh is the 'gotta catch 'em all' goal taken to its most literal tee, just, true to the anime, they've just gone straight in first time without thinking through what substance to give it beyond that, needing to add stuff to it later on.
Ash's 'classic' team I can also see their aim, all the non-Galar mon on his JN team were consistents throughout the show for Pokemon kinda out of his league, and even starting off in antagonistic roles the first few times round. We actually saw how they slowly became more and more humanized and accessable as series continued, culminating in Ash finally getting them. Still not always amazing handling, but an interesting progression of three Pokemon and their use throughout the show.
Legendaries/mythicals have a similar direction, though I think the issue there is more down to Goh's premise not really letting them get development. Shaymin and Nihilego were more interesting takes on this, if still kinda flawed. I do wonder if Articuno might have been a better choice for JN spotlight than Suicune, especially considering its similar role as a developed consistent (see Noland's Articuno), though fair enough for the Regis. Now if Goh could just let his get spotlight already.
And of course the character returns which were an obvious choice from day one, but could have done with being less fleeting and again, having more substance to them. I feel like Dawn's weren't bad but considering she hadn't as much to show off, maybe they could have replaced her in one appearance with Iris to make her own development more gratifying. The Master 8 arc really makes it feel like we should have been following her more.
