I kind of felt this arc to be too similar to the Skypeia arc.

The Straw Hats go to an island they couldn't normally get to since it's straight down (Skypeia was straight up), they find the kingdom and they get captured (the Shandorans tried to kill them), the main villain has a few more allies with him for them to defeat (Hody's pirates/Eneru's priests), the main villain is trying to take out the king (Eneru already did that, and Hody didn't quite successfully do that), Robin finds an uber-historic poniglyph, Gold Roger paid a major visit there, and both of the main villains have a fetish for a giant ship.

Some of these things are actually the same but reversed, but you gotta admit they are pretty similar.
