I'm going to have to go with naruto for my one and only anime to watch because it's such a well crafted art with action packed battles, thrilling plot lines, and awesome characters.
Ever since I picked it up I could not bring myself away from it. I love reading the Manga and watching it come to life in the anime. Every character experiences growth and you come to care about every single one. It's amazing how it can take you on a Rollercoaster of emotions and make you feel things you never thought you could.
Kishimoto-sensei gave us a true work of art, it's timeless and will never get old. I absolutely love it and I can't get enough of it. It makes me want to be a ninja and seeing naruto, the main character, go from the underdog to one of the most powerful Shinobi ever is really inspiring.
