Worst ending to a manga I've ever read so far.
Tsuna didn't fucking change at all, he just reseted back like he always does at the end of arcs and then they even go and acknowledge that in the actual manga. But for some reason it's all fine and dandy that he didn't change anyways, because he has friends(which he's had for a long time now)! Haha, dear god this shit fucking sucked.
Reborn was an awesome character until the very end though so he's the redeeming factor of this pile of vomit, despite some irrational things Amano had him spout for this shit ending to come true.
Overall this crap gets a 3/10 from me, so glad it's dead and over with now.
