I think my favorite thing about Netflix One Piece is that at first, it appears that they've made Zoro much smarter than he is in the anime. But then over time there's this dawning realization.
he's not smart.
He's just very confidently stupid.
He comes across as smarter because he doesn't talk enough for it to be immediately clear that his brain is just a hamster wheel with a hamster that only runs if he's holding a sword.
Zoro only looks smart because he's standing next to Luffy, who helped set the standard for shounen-protagonist brain damage.
