I was liking this arc at the beggining... now I just want it to end... year of Sanji my ass.
In fact, OP got a lot worse for me. I was re-reading it from the start and it was fucking fantastic, specially from Arlong and forwards... it goes fucking dowhill starting from Impel Own... the pace gets all over the place, fights get boring with so few panels... every fucking arc feels like a drag, so many characters I just want to see dying or not there. So many things happening at the same time.
The worst thing for me now post timeskip (and Impel Down/Marineford) are how bad the battles got. I didn't like any battle after Saobondy, in fact...
Maybe I'm done with this series... sorry for the rant guys.
On the other hand, I'm loving Promised, BnHA and Nanatsu.
