Yeah, that episode was pretty poggers.
Aside from maybe the flashback and some of the fake out death stuff, I don't believe the episode really dragged too much. The direction was pretty tight in the first half even if it wasn't as animated as the second.
Animation wise, this episode is insanely good, especially the second half, which is pretty much non-stop movement 95% of the time. Tu Yong Ce knocked out of the park with pretty much every tiny little bit of action in this episode.
Its absolutely insane how well some of the stuff he did was. Its not just impressive because of how much he animated, but how well it was animated. Scenes like the Brachio Bomber by themselves would have been enough to make an episode noteworthy, but the entire second half is just filled with really nice action animation that doesn't stop. It makes for an absolutely fantastic animation director debut.
The animation also did a great job of selling a lot of the comedy through character acting and visuals, which Oda is highly dependent on. The timing of the jokes landed really well thanks in great part to the animation.
Overall, awesome episode, decent direction exalted by fantastic animation.
I have frankly zero expectations for next episode. Literally none. The animation looks like its going to be totally outsourced to a fairly meh studio. I don't expect anything animation wise, and I think the virus looks really ugly with that green. I'm thinking a good director is needed to make that sort of effect work, because right now, its not doing anything for me.
