I do like Max, but that's because I saw him having depth and reasoning for his actions most of the time, while also being snarky and such: I think Bonnie is cute, but outside of the Flabebe episode, she hasn't really shown any depth and the like, which is why I'm not a fan of her if that makes sense. If XY027 Bonnie returns again, then I'll like the character, though.
Alyson Rosenfeld is the worst VA post-4Kids for a newly introduced main character, IMO, so yes: Mariya Ise is at least decent as Eureka in the ORG JPN Version, but I still don't like the character much.
