Nah, Acts 1 and 2 of Wano were received very well. Zou was also well-received, especially since it followed Dressrosa, which had been dragged out. There was fatigue from it. Jack's introduction was big, since it was our first billion bounty.
Some of the Zoro fandom weren't interested in WCI, though. I fall into that group, but I didn't see WCI getting general hate until later on.
