From Day 1, Kishimoto has been aiming for one goal: Overtake Dragonball Z as the greatest shonen battle manga in history. Well, ladies and gentlemen, he has done so. Akira Toriyama, eat your heart out.
Story (5) - The story of Naruto evolves throughout its development. As a manga nearly nearly 600 chapters long, it has had a long time to grow and change. Fundamentally, Naruto is about the characters Kishimoto has created for us - the story evolves to suit their needs, not the other way around as many others do. There are many philosophically valuable themes throughout the series, and I have learned many important lessons from this series.
Dialogue (5) - Naruto has some great lines in it. As a writer, Kishimoto manages to blend the gags, quirks, gafs, and epic lines into a series with some of the best dialogue around. Kishimoto rarely, if ever, abuses dialgoue. It is utilized effectively for various narrative purposes, and I find little to no faults with it when charitably interpreted.
Animation (5) - Naruto is a gorgeous series. The character's designs are instantly recognizable, and the style is unified in a way that allows artists to emulate with varying degrees of ease. Backgrounds are rich and beautiful, and the inclusion of feudal japanese aesthetics is just wonderful. The battle scenes are the best in the business, hands down. The intensity of the story is conveyed through the medium of the drawings.
Entertainment (5) - Naruto is just plain fun. I don't understand people who claim to dislike this series. It is often as though they're actively choosing not to like it for various motives. The entertainment levels are always high, especially for fans of pure shonen battle manga. Absolutely some of the fights have gotten my blood boiling in ways that Dragonball never could. Why? Because of my investment in the characters and their relationships with one another. Kishimoto does everything he can to have his characters put something on the line with every fight. This kind of investment goes far beyond the purely good and evil of a series like Dragonball Z where the enemies were always alien, with Vegeta being the exception to that series.
