I liked most of katekyo hitman reborn,was really good comedy/action manga yet this didnt felt like a ending at all,they just chosed the normal series ending,in wich they dont resolve anything,Tsuna still sucks at almost everything and dosent want to become mafia boss,has not resolved his sentimental situation and well nothing,the only thing solved was that now the arcobalenos can actually age and he fixed the system that allows evolution and life itself,awesome....if it werent for the fact that it still let all the holes in the main point of him becoming vongola 10th I was thinking that they woud actually retake the point of his classes to become vongola 10th and that we will actually see him change into a reliable guy at least if it was made shortly to be shown in 2 or 3 numbers making use of timeskips or something,but this was like "I runned out of ideas so this is the end and now Im gonna work on something else"
