I really liked the episode because I really love Cheren and he was really adorable in this episode.
Also I don't think Oshawott deserves the hate it gets. It's cute and tries hard. It shouldn't be berated just for being weaker than the others. Ash needs more Pokemon that don't bend the plot to their will every time they fight. It got old 10+ years ago and they're still doing it. I'm happy that Ash lost.
The episode was full of cuteness.
