Well... with almost everyone in this board hating on this manga now..... I believe this is somewhat appropriate..
What part of the manga did you hate the most? Aside from the ending....
Shimon Arc for me... Daemon Spade and the cheesy as hell Vongola Gear just ruined that whole arc for me.
I actually would have preferred it if Vongola Primo DID betray Shimon Cozart and Tsuna has to go out of his way to fix his ancestor's mistake or worse, put the Shimon family out of their misery.
I also hated how Tsuna beat down a freaking Time-Space Controlling False God which was Byakuran and proceeds to get curbstomped by a middle schooler with probably much less experience than him.
