Actually I thought it was very impressive with Usopp telling everyone to jump into the sea. And also the way it goes in the end was really sad. I'll tell you, never in my life have I ever expected that I would be that sad over the loss of a ship. Heck, even if it were my own bloody ship. Oda did a great job here imo, and I always expect the best from that guy. I thought this arc's action was drawn out, like it was in Skypiea, but he always makes up for that afterwards. But this arc owns skypiea imo, mainly because of all the great parts in it. Really, Usopp's fight with luffy, how they saved robin, and the whole going merry thing were the top 3 things that made this arc really special. And those are 3 things that will be remembered about this manga, not just the arc. Well, for me anyway.
