The fact that OP hasn't devolved into an inconsistent mess full of wish fulfillment and a complete lack of foreshadowing still gives me hope. I'm reminded that the first ~100 or so chapters of One Piece aren't overly great or anything either. Granted, we're now nearly 200 chapters into the post-TS story, and it's not like at the very beginning where we'd yet to touch on the meat of the plot at all, but I'm sure OP will reach its former heights once more.
