Filler-Tastic, but pretty great
My overall complaint is that the battlefield looks too empty, but they kinda have an excuse, its a colossal frozen sea and everyone is running ahead, after all
They'l have no excuse when Luffy arrives at the Plaza, though
The sword strike was handled alright, it wasn't as surprising as in the manga, but it was a little more tense, so no problem there, I also liked Akainu's face after the slash, you devil dog, you
The fact that the Mihawk VS Vista fight was animated well and once again, showed a great small strike of Mihawk (after it being deflected), only pisses me out even more about last episode, Toei did great with this 90% filler episode, without relying on too many reaction shots and stupid dialogue, but awful with one of the most important (and awesome, IMO) chapters in this arc? For shame, Toei, for shame
