Wait, what? How is that a BAD thing??? It's awesome that sensei is bringing everyone back to wrap things up with a nice bow! How many storytellers have utterly failed in that regard?!

I think, if I remember correctly, they complained about how bringing back many characters at the last part of the series is something cliche, that other mangakas specially the long running ones have always done the same thing, aside that it makes the story longer. Over the years, Sorachi has been deviant with his themes and antics but somewhat this time he's doing what has been done already.
Honestly, I have no complaints since this is the only long running shounen that I completely immersed myself into. I was a fan of Naruto and Bleach but I didn't last long.
I saw on tumblr that some people are quite upset since the story is obviously getting longer as more characters are highlighted and added to the war. I seriously don't care. I already saw the spoilers and I'm already to shed tears next chapter.
