I certainly have been enjoying it! There's many things I like about the arc.
For one Doflamingo was cool to begin with, seeing more of him is good. Then there's Franky getting to shine. Franky is underappreciated (And underrated in terms of fighting ability.)
And though it seems many people don't like Rebecca, personally I DO like her.
I also have some hope that this arc'll finally put all that powertier bullshit so many OP readers seem to get lost in to bed. I'm not sure if it will happen, but I certainly HOPE that Usopp'll find a way to beat Trebol through smarts. I HOPE that Rebecca'll find a way to beat Diamante through smarts. Maybe neither of those will happen. But I'd love it. (And honestly I don't think OP is HUGELY tier based, yeah there's clearly certain leagues of strength, but it's not an ironclad 'power level' sort of thing if you ask me.) But eh, if nothing else I'd be happy with Franky kicking Bastille's ass too. (And why not, he's been doing very well rampaging through Doffy's executives two on one so far.) Or even if THAT doesn't happen, I like how Zoro showed more of his goofy side again with not knowing right from left and that Pica'll probably give him the first REAL challenge since the time skip. (And I like Pica's power alot too, manipulating this huge helms deep-esque castle to fight.)
So you know... even if alot of things I'd like to see won't happen, it'll have other stuff I like.
That and I like Bartolomeo alot too. (And some of the other colloseum chars like Cavendish and Chinjao as well.) And I like Fujitora even more!
I also like that Big Mom actually went after the ship (With an awesome giant singing ship!), instead of sitting on her ass like a final boss in a videogame. I like it when major villains are proactive like that. And I'm curious to see where that'll go.
So yeah, I'm liking the arc! Best post-timeskip arc so far. (Though I did actually quite like Punk Hazard! (And it's fun to see my favourite chars from that arc (CC and Kinemon) back in this one.)
