Not a bad episode. I liked some parts but not others.
It was good to see Dragonite all cocky to begin with, then getting a serious slap in the face and having a tantrum when it realised that the krok was tougher than it expected. It having a tantrum was unexpected though, but it was good to watch.
Krookodile is awesome. The evolution didn't really feel forced either. And at least the sunglasses match its colour scheme now, so I don't mind them as much (though they do annoy me, please get rid).
I didn't like how Pignite couldn't land one single hit on Serperior. I get that it's supposed to be really fast, and I don't even care that Ash lost/Trip won, but seriously, not a single hit even when it's surrounded by fire? Not one? Kind of infuriating for me to watch really.
I just hope Alder and Bouffy knock Trip down a peg or two.
