Dude, I think the Galarian forms might be my favorite things in Gen 6 so far. Galarian Weezing is PERFECT for a British region, and as I understand it, badgers are quite a thing over there (see: Hufflepuff, Helga). So taking the badger(ish?) pokemon they have and sprucing it up for the new gen is just a slam dunk to me.
I also think that cross gen evos never quite worked as well as we wanted them to. Gen 2 had some good ones, but Gen 4 went way too far for my tastes, and I think a lot of people's tastes. I think giving regional variants and then giving THEM new Evos makes a TON of sense. I think you get the nostalgia for the old pokemon, but you don't make people feel like the old things they like are ruined if they aren't into the new evo. And if they are, hey, all the better.
