I never got into Naruto, but to flat out say it's bad is pretty excessive. I still prefer things like DBZ to it, but there's times I think about the power scale in DBZ. It's honestly f'd up. lol Like from the saiyan saga to the cell games, These dudes multiplied their power levels by like a trillion. WTF is that about.
I could be mistaken, but at least Naruto didn't do anything like that.
