I could complain that they're still using midi at this point instead of live instrumentation.
I could complain about the lack of voice acting.
I could complain about the fact that the 3DS hardware is very clearly holding this game back severely.
I could complain about all that, but...
I just can't find it in my heart to. Pokémon is FINALLY evolving, at least visually. And you know what? For this game, just this once, I'll take that. Baby steps.
