It's not bad. All the older otaku call it crap, the noobs praise it like a god, but it's just decent.
Very good characterization, diverse to the point of being hard to keep up with though.
Interesting story to back it up. A few cliches, but not to many.
The only parts that I can really complain about are the dub and filler.
A few of the voices(paticularly Naruto's) just make me clench my teeth.
And the filler, THE F*%$ING FILLER! An episode or two in between arcs? Not bad, somtimes enjoyable. BUT 90+ EPISODES OF FILLER?!
My advice? Watch it. But after the battle at the Valley of the End, go find episode 120 and just skip the filler completely.
