Actually, Naruto doesn't repeat the pattern of “Here comes a stronger boss!” of DBZ. There's actually an overarching plot, and villains are foreshadowed. And there is not Space Flea Out of Nowhere. The bosses seem to get stronger simply because the main characters are finally getting ready to go out into their playing grounds. In the past they're just kids fighting mainly the bosses' underlings.
well, that is good at least. i'm still not a fan of the large gang of 8 friends all rolling together. “bleach” is a great example of this. my roommate loves this series too. it's like every other episode they add a new buddy with a special power to their group of friends and talking dolls to follow them around.
it's just become so common place in modern japenese comics and animation to overload characters on a story. this guy is fast. and this guy is good with swords. and his sister can see dead people. and her other brother can control the wind. and this girl is blind. and her girlfriend can manipulate time and space. and this guy is gay. and this girl can control sand. and this kid has the heart ring that lets him talk to animals. it gets to the point that i don't even f__king care anymore.
i'm not against japanese stories. i love DNA2, I"s, dragon half, & trigun as series. very solid with a core of 5 or so main characters and each one is VERY different from the next….even though 2 of these were written by the same guy!
