I don't mind the epilogue, but I do feel like he shouldn't have ended it how he ended it. The ending itself felt rushed, didn't tie up a majority of the loose ends, and just felt unsatisfying.
Im not going to sit here and complain that the final fight between Naruto and Sasuke was "to short" and that I expected a 15 chapter epic final fight. But I do feel like the Kaguya fight could have been half as long, even cut from the manga entirely and instead used those chapters to give a fitting closer to the characters, the war, and the loose ends. [and if by doing so there just happened to be a few extra chapters of the final fight, I wouldn't mind that either

].
I love this manga to death. Im not upset in any way at the ending. I think Kishi, after 15 long and hard years, skipped to the end in that final stretch instead of giving the ending the love and care that he has been giving the rest of the manga all these years.
