Wow, I didn't expect the live action to exclude one of my favorite characters, Gin, and still make me love the episode. From beginning to end, it's perfection with very, very minor issues that don't affect the plot at all.
The dialogue was fluid and immersive, something that I felt the series lacked until now. The acting gains another level with the kitchen; I absolutely loved Patty, Sanji and Zeff. Mihawk might be the only one who acts too theatrically, but who cares? It's Mihawk, he's cool no matter what he does.
I see they tried to replicate the Zoro scene in the manga, with posture and all. It was emotive, but they should have aimed for a more natural approach to avoid making weird shots.
Spectacular non-canonical content. The conversation between Nami and Zoro was perfect; I can imagine it in the manga like it was there in the first place.
The first Garp scene didn't even bother me; we finally see some of Garp's real personality. Great stuff. My only complaint would be Garp's argument about the warlords. While half of it aligns with what the real character is, I don't think he would be collaborating with warlords that easily. It kind of contradicts his fierce speech back in episode 2. The scriptwriters tried to experiment, and while the content is good, they need to take care of the continuity so they don't contradict themselves.
That would be it, really. Top-notch episode that actually made me feel like I was seeing a top-tier series. It's amazing they could pull this off despite it being a live action. Of One Piece. Cheff kiss... now more than ever.
