Wow, this is the first time I've read something I 100% agree with here. For quite a while, I had been trying to make sense of why I began disliking the story after Blacksteeple Castle, and this is a pretty succint summary that matches my reasoning. The questions surrounding everything introduced just continue to pile on and are never answered. As you said, the characters begin feeling unutilized, unnecessary, and undeveloped, dragging the story and worsening the experience. For me, its gotten to the point where it begins seeming like filler content to pad between gyms. I definitely think that the story has to slow down, begin explaining, and stop leaving too many things shrouded in mystery at once. I absolutely love the effort that has been put into improving how everything looks, but reviewing the dialogue should definitely be given higher priority in my opinion.
