The bottom of this list hurts me to read, but thats besides the point. I think Skypiea was amazing. I think people who watched the anime may have had a worse experience than I did, because for me the arc was just really fun and had a lot of interesting world building. Fishman Island has the worst fights in the series which means whenever I reread fishman island I skip them, which makes it not as bad as I remember.
Also It's not just you, but I hate when people split arcs like water 7 and enies lobby apart. They are one arc, and enies lobby just doesn't even stand on it's own without water 7.
