Absolutely fucking awful. This is what happens when you attempt to stretch like 7 pages into a 20 minute episode.
I knew the anime had pacing issues so I stopped watching it back in Dressrosa, but I figured lemme check it out since this scene is so epic there's no way you could fuck it up. But Toei never fail to go above and beyond.
Even beyond the excruciatingly slow pacing, the design choices are baffling. Wtf was that shitty red aura around Luffy? When did Luffy learn Skywalk? Between shit like that and every sentence, action or minute detail taking a solid minute of freeze frames, gasps and PowerPoint animations, honestly it'd be harder to do worse.
If I was Oda I would get out of any contract he has with the studio until they do better because this is making his work look like garbage.
