Personally I haven't minded the island arc so far, I mean it has gone on a little long and I could have used more of Marah trying to mess over the MC and then for him to put her in her place, happened a little too quick for me. Also, I expected there to be a bigger payoff with that girl's father who tracked them down to the island, only to have him immediately caught and imprisoned is kind of a waste. It has been more fun than being stuck on the death island with Kira though, now that was unbearable. And I'm glad they addressed the whole thing about the MC being able to get back to the island, I mean it would be completely stupid to have him go through these trials, become the new ruler and then be like, "Peace out, gotta get back to the main land, good luck with your whole tribe stuff." Plus it's never a bad idea to have a tropical island where you can go hang out, bang a bunch of chicks and be worshiped like a god whenever you want, I mean I can't imagine anyone being offered that and be all like, "Nah, I'm gonna pass."
