I agree with this person sorta, as of now. A friend of mine REALLY wanted me to watch Naruto so I finally caved. I have nothing better to do this summer anyway. So I torrented every god damned episode (english subs, japanese dub... fuuuck I've seen an episode of it on CN, and I cannot stand Naruto's voice). I just got to episode 102 and it seems there's lots of filler ahead. The episode where they try to get Kakashi's mask thing off was pretty funny, but if the next 20 or whatever episodes are like that, it's going to get old quickly.
I was liking the show a lot more at the beginning. Especially the Zabuza arc. The exam arc was all right too, but after they finished going through the forest is where it sorta felt like it started slowing down a lot... And now they bring up uh... Sasuke's brother for a few episodes, then throw him behind the curtain and bring out Orochimaru for a few episodes and now we've got filler. Huh.
