ONE WORD. LEGENDARY.
I totally fell in love with the anime. the story, characters, and sound effect. Also i recommend watching Naruto before Naruto Shppuden, cause you might wonder and have many questions, even though with time there will be some flashbacks, but i wonder if that's enough. Yes, Naruto was a little boring, there nothing new, its fights and everything. but atleast theres some info about naruto's past.
I started watching Naruto only because of a post where the kid naruto is saying he doesnt have anyone at home who will wait for him and there was a second pic where there his child is saying " where were you, i was waiting for you''. I means the first pic was from the vey first episode of Naruto.
anyway. i dont think i can tell anything without giving any major spoilers. but its different and amazing. but theres many arcs of filler episode. dont always skip it. naruto shippuden is indeed big 3 title deserving anime.
