User blog comment:Neowitch/Worst Story Arc/@comment-4904935-20120608064327

My least favorite arc is Skypiea, but I won't call it the worst arc because we got to know freaking cool villain like Enel! Plus, we got to see the ruins of Shandora with Poneglyph related to the ancient weapon Poseidon! From the Little Garden arc, we were introduced to some of the Baroque Works network members and the giants :) Loguetown arc: Smoker, Tashigi and the most importantly Luffy's father, some history regarding Roger execution and so much more from this arc!  We got Chopper from the Drum Island arc. The Fishmen Island has a few back stories, and one of them was connected to Nami's past, the energy steroid, Luffy declaring FI his turf and challenging Big mom! IMO, each & every arc is important part of the storyline of OP!
