Well at least they have some Pokemon opinions... though it doesn't sound like that's their main concern but whatever.
1. The Snorunt family is overall an odd 3. They look nothing alike one another and their only connecting theme is they're based on ice spirits. And while I agree Glalie isn't exactly popular here too (design is a bit bland and its stats suck, Mega Glalie gives it much needed improvements), I have to wonder if they only said that because some of them think Froslass as "waifu" material (even though she's based on a yokai which kills people by freezing them... and Froslass in particular collects its frozen victim as ice statues).
2. Yeah, that's BS. You're not making the new Pokemon seem more powerful you're making Ash and Pikachu look incompetent. I know you can't have Pikachu steamrolling through all its opponents but at least provide a good reason and decent battle from it.
3. What was wrong? And please don't tell me its because they're not as cute as Torchic because that pretty much describes all the Starters (I'll give them Comdusken looks a bit ugly but Blaziken is awesome looking).
4. Let's see: Pikachu, Swellow, Sceptile, Corphish, Torkoal, and Glalie. I can see that being an odd combination (aside from Sceptile not many of those Pokemon are popular) but type coverage wise it looks pretty nice. Though looking through the Gen III Pokemon I can't really find any I can say Ash could have gotten that would have changed all that much of the misfit team. Spheal? Trapinch? Absol? Honestly if I was making the team I might have come up with a similar format if given the restrictions were they (needing to have Pikachu, Ash only having one Starter, his Pokemon need to cover a variety of types, no pseudo Legendaires, no Pokemon which are signature Pokemon of another trainer).
Sinnoh: Who would have Leafeon and Glaceon? I mean I know Brock has expanded upon his type specialty but still. Also both that gen's Eeveelutions would have probably felt like they were forcing them on us (though oddly Dawn's Eevee didn't evolve until he cameo visit in BW). Also I like Brock's Croagunk, who doesn't like Brock's Croagunk?
Only odd choice for Dawn was Swinub. Yeah it starts out cute but they had it evolve so that didn't matter. But then again that did give her a powerhouse so in the end I think it worked out. Though it was dumb how they gave away Ambipom.
Unova: I can give or take some of the choices but my main problem with the Unova cast is how they didn't evolve a lot of them. Ash went into the Unova League with a Oshawott, Pignite, Snivy, Scraggy, Palpitoad, and Boldore. All of them should have been at least been middle evolution and most of them fully evolved. Fine, get Oshawott is crazy popular but I don't see why they didn't evolve Snivy and Scraggy (Scraggy evolving might have even aspire Axew to evolve being they were close friends). Palpitoad and Boldore probably should have evolved all the way since they're a bit of oddballs and being fully evolved would have given them some notoriety (especially for Palpitoad since Oshawott was going to be kept in its basic stage it would have filled as Ash's Water-type "powerhouse").
Iris, yeah, as
Darth Manaphy said she's suppose to be a Dragon Master... yet her strongest Pokemon for a long time was Excadrill. Why not a Druddigon, you didn't do anything particularly special with it and she had one in the games. You made a backstory involving a misunderstood Druddigon which the Elder calmed, change it so that it was Iris who made a connection with it, they battled together but after losing to Drayden it went back to being unsocialable as it felt it failed Iris. They could have also had her befriend a Deino which then evolved to a Zwelious and due to it having two vicious minds became uncontrollable, but I can see them not doing that since at that point they were probably still planning on getting Team Plasma involved.
No real opinion on Cilan's choices, just seemed kind of there. Crustle was the powerhouse and Stunfisk I suppose was good for a laugh though nothing remarkable beyond that. But he pretty much was there just to assure Ash & co. didn't get completely lost and starve.
