Don't you think Kishi should have take his time. For sure he said Naruto will have less than 100 tomes. But now, if you think about it (the last chapters), it almost like if he wanted to get over with the manga:
Naruto and Kurama being buddies in hours after 16 years
He mastered the TBB in seconds, he had been failing for at least 15 chapters
He had been entrusted with the souls of 7 (6+Kurama) of the TB and is truly on his way to be the 10 tails' host
Even I can find valuable reasons to those but I still think things are going way to fast. What about you?
