God, I remember all the idiots saying Sun & Moon had "bad animation" by cherry picking in betweens. These people still exist. What they don't like is Ash's character design, but the designs being the way they are has allowed for such fluid animation on a consistent basis. Remember speedline backgrounds that look straight out of the 60s? Remember when "animation" would consist of a quick pan of static character art shouting with the only movement being two frames for the mouth? It really says a lot when we considered the dynamic CG backgrounds of XY to be amazing just because they weren't speedlines.
OLM really is great. While Game Freak rests on their laurels and releases yearly mediocre games because they can sell on brand name alone, OLM tries to go above and beyond with a weekly series for children, an anime demographic that one could excuse not putting high quality animation into. There's real passion right there.
