It's alright I guess. I thought it sucked the first 40-ish episodes or so. It got better after a while but it's nothing special and very overrated in my opinion, I'd rather watch another ninja anime. I could go on for hours pointing out everything bad with it but that's maybe not the point of the thread. I kind of like the story and what's happening... when something is actually happening.. but the animation quality............. eeeeeeeeeeeh nope.
Naruto is pretty cool, Sasuke is meh and I don't like Sakura. My favorite characters are Lee and Orochimaru. Orochimaru was the only reason I didn't stop watching after episode 50.
Unlike most people I actually don't mind the fillers (as long as it's not recap-fillers but actually fillers with new content). I just like some random funny episodes like that.
Sadly it's almost unavoidable to hear spoilers about Naruto so I already know how it's going to end and stuff, oh well. I haven't seen Shippuden yet, only the original show.
PS. Opening no 3 with the kid singing is sooo good. I sang along every time.
