It absolutely was not just ok. It was some of the smoothest art + animation from toei. Only thing is the entire episode was consistent, so the scene didn't stick out like a sore thumb. Only thing you can say is they should have paused for longer when Kizaru made the face, to put more emphasis on it.
It was just another moment 😂, you're acting like this scene was any different in the manga, or lead to something greater. It wasn't even a double spread.
The only difference in the manga is it came from left field, so the shock value behind it carried the scene, whereas Sanji fans like you were anticipating this scene for years in the anime.
There's really nothing wrong with the scene, it's all in your head. If you were watching anime only that scene would be a standout scene because of the feat itself, rn you have already taken the feat for granted so the only thing you're looking for is some over the top animation to separate itself from the rest of the episode. But if you just clip that scene on its own, it's done exceptionally well. Great art, great animation while keeping it simple, .and for once even great sfx. Whoever was behind this scene did a great job at showcasing Kizaru's beam as well, it's moving like his light beam should, and Sanji kicking it sounded so impactful I'm so tired of the egghead arc showing Kizaru and his light moving all wiggly and shit.
