I think, if this had been a longer arc, and that the fuuma ninjas weren't throwaways, Kagerou's transformation thing might have been cooler, because we would have been given a ninja version of "the ugly duckling." Of course, that comment will be flamed by prepubescent posters claiming that a girl turning into "t3h fairy was gh3y."

Also, on the killings of the two Fuuma that tried to assault Oro, wouldn't it be cooler if it was shown that Sasuke did it, in true Ninja fashion, i.e. from the shadows, so we didn't see him do it?
