i started really liking naruto after neji asked naruto in there fight "why fight a hopeless battle trying to deify your destiny" and he said "because everyone called me a failure, ill prove em wrong"
I was sold instantly off of the show due to how deep it was. The Zabuza arc was great and the first fight where I totally flipped out was Rock Lee vs Gaara when he first opened the gates.
Honestly it was when Pain fought Naruto. I was at a friend's house when I saw his little brother watching Naruto. I thought it was gay, until I saw Naruto throw the rhino. Secretly I went home and watched it and my life went downhill from there.
