One would think a kick to the balls from Sanji would be crippling, but Caesar apparently is tougher than he looks.
Man, that was about as good as anyone could have expected. A very good animation team behind this one. That Kaido reveal rocked, including those extra touches like that look of stark terror in Hawkins' and Co's eyes. Well directed overall so the filler never really got in the way.
One notable thing about the artwork is that the artists and animators clearly weren't working off of any facial model sheets some of the time. Nami in particular ended up looking a lot like Asuka from Evangelion, though I think the combo of the outfit and the long hair owed a lot to this particular doppelganger effect.
One good bit expanded from the manga was Nami falling on Brook. In the anime, they take it a step further by having Brook dive to her rescue, only for her to selfishly use him as a bobsled as he cries out is disbelief. At least she said thanks!
There's also a slightly bizarre bit where Sanji attempts to embrace Nami and while he's diving in the air her palm smack to the face keeps him suspended in the air.
