I've seen the japanese DBZ and of course I'm a fan of DBZ but it was still very predictable. Get stronger defeat new stronger bad guy. That was basically it. Regardless of it being the cut or uncut version the storyline was the same. And I've also watched many other anime, some with a good storyline and some with not so good of a story.
As for Momiji, um Naruto's storyline cliche and predictable? Where else have you seen a storyline that in anyway reflects Naruto's? UM.... nowhere... that's right. If you have please give me specifics. I challenge you to. Maybe you watched like the first 3 episodes or some fillers, but the storyline can not be compared to anything else out there because it is just THAT good. I know people are entitled to their own opinions and to say you don't like Naruto for your own reasons is fine. But to say the storyline is predictable is just ignorant and stupid. Like Cloudane said, it is popular because of its greatness. It is the very reason why a series becomes so popular. So predictable? Cliche? Don't think so buddy but good try. Just keep on watching DB.
