The new art style looks more Yo-Kai Watch-esque to me, and I have to admit Yo-Kai never grew on me even after watching a few of the English dubbed episodes of that series. Ash's new design does kinda remind me of Steven from Steven Universe as well, notably the hair.
I can understand about the upcoming Sun/Moon anime being considered bad because of the new art style, which looks to me that it bears an uncanny resemblance to the Yo-Kai Watch anime and Steven Universe, and am also just as concerned about yet another complete reset of Ash because of him going to school. Not to mention that of course, everybody's all sore about Serena not joining Ash in Alola (a perennial pattern that I think has become stale.)
I actually don't mind the changes because Game Freak are experimenting with new formulas. The Sun & Moon anime will definitely be a flop for me since I don't like how stupidly drawn Ash's face is, and the possibility he's going to do another complete reset like in Unova.
You know, if it weren't for you (and a couple of others I know elsewhere online), I probably wouldn't even be a fan of Oshawott or Dewott. (For some reason, I'm not too crazy about Samurott, though.) Then again, I'm a sucker for cute Pokémon (despite me being a male.)
