i think this arc is cool
kakashi is just mysterious and everybody wants to know how he became who he is today

i dont really mind how long this would be, but it would suck to just rush it through and leave it unfinished and return to the stroyline of naruto where they left off

i believe that this arc ties in somehow to what has recently happened in the past few chapters in the manga, like the relationships of the characters

it would be awesome to see more of yondaime and how he is, though the main focus is on kakashi
