I'm not exactly sure what the anime was going for having P1 essentially ok. It makes the whole reason Sanji got involved in the fight pointless, since P1 would naturally go back to destroying everything in order to find him. Bad move, Toei.
Besides that, the fight sequences did look good. Sanji's RS colors are top notch. Black and Red are always complimentary color combos. The anime also expanded on Law's Germa fandom. Law's not a character I particularly care for, but I hope his fans enjoyed that.
Next episode appears to be Robin focused, elaborating on her game of cat and mouse with the Oniwaban.
