Go into to detail why it was bad
Okay.
We went from the annoying previous "we get 5 second shots of every character face as the look at each other after one of them moves a muscle" to the extreme opposite.
Extremely fluid animation that:
- Is too over the top (what the hell was that last attack from King in the anime? What are those auras? Why does every character seem to fly from time to time? Why does the ground get sliced into cubes whenever a swordsman swings his sword?)
- Deforms the characters. Deformations that don't even serve the fluidity, they're just there. The way bodies, limbs and faces deform, their contour looking like liquid... I remember S-Hawk's fingers for example looking like waves instead of, you know, fingers with an edge. It's a random example, it happens in almost every shot. It's not far from the Pain vs Kyubi scene, just more fluid.
- Straight laziness (back to Zoro vs King, what was that last attack? Zoro just becoming a green line drawn on Paint?). I call it laziness because the studio can do it well when they want.
- Things too fast for the eye are passed off as the coolest animation trick ever. During that same fight, when King and Zoro prepare to attack each other at a certain point, as they powerup their past forms flash quickly... at a frame per picture and inconsistent lightning. It's cool seeing the frames, but it added nothing on the watch itself.
- Prolonguing the fights with bullshit. Lucci vs Luffy. What was Lucci doing running all around Luffy like he was Bellamy in Jaya? Since when has that ever been remotely Lucci's style? What purpose did it serve Lucci to run in circles for a minute far from Luffy to, in the end, just run in a straight line to him from the front after tiring himself out? Why did he run on all forms in awakened mode like a leopard? That's, once again, something Lucci wouldn't do. The strength of hybrid modes is to use human techniques with the augmented attributes of a zoan. Lucci's skills in rokushiki are a huge % of his strength, and he makes full use of them in hybrid. He's faster using soru than he is running as a leopard, which makes the scene even sillier.
So, enjoy the anime if you guys want, but it's definitely not objectively the best One Piece has had. I personally don't watch it precisely because I can't stand the animation (which to be honest started way before it was animated this way).
I don't watch a lot of anime anymore, but from the limited pool I have actually watched, Kimetsu no Yaiba has the best current animation.
