I honestly don't understand why people have whined so much about FI, and this chapter.
I loved it. I honestly just think that people were expecting way too much, like Oda was going to change his style just because this arc had been hyped for so long. The crew kicked some ass, and are now celebrating - eating meat, drinking sake e.t.c., which is pretty standard for any other OP arc, and I don't think anyone here is opposed to that, since that has been "most" arcs have been with the SHs, and this was the first arc like that for a long, long time now.
At the same time, we got more revelations regarding the bigger picture; voy boy, the void century, ancient weapons... Major plot points that have been in play since the start of OP, and that we have finally gotten some (partial) answers to.
