After watching the first season I was like what else are they gonna show in S2, it'll be a drag. And then I saw a review here explaining why I should, and I did watch S2. Would have regretted if I hadn't watched it. Would recommend watching both S1 and S2 together. For a person who waits for One Piece weekly, I am very picky about the anime I watch on other times. This was certainly a super, feel good watch. S1 is definitely better since you are freshly introduced to the concepts and the characters, but at the end the anime isgood as a whole with both S1 and S2
