I used to be interested in Naruto because I thought it actually looked cool. Then all of a sudden, I just stopped watching it. A friend of mine picked up on it and mentions how cool it is and while I'm going "uh-huh" knowing pretty much everything he was talking about. It's pretty interesting actually, because this same friend expressed disinterest in naruto when I was into it. But he's gone nuts over it because of Sasuke and how he shares common characteristics with Sasuke and stuff, so yeah. I think by that time, I realized how overrated Naruto was and my dislike of the series started from there.
I watched a few Shippuden episodes, and had a few character favorites, but honestly, the series never really appeals for me anymore. It hardly has to begin with since I was only "into" it for about a short while anyways.
