Pretty self explanatory; anything you love in One Piece that you think too many people hate and was actually pretty good, despite what the majority of common opinion thinks.
For me, it was the Skypiea arc. I heavily enjoyed the setting, the plot, the fights and general set-up and its overall detail that was present throughout the arc. However, lots of people seemed to hate it, but I beg to differ.
...And no, it's not a "filler" arc, so don't start. I have no clue where people get that idea from.
So, what are things you love in One Piece that everyone else seems to hate?
