It is focused on the hyperactive adolescent of Konohagakure (Village Hidden in Leaves), Naruto Uzumaki, and his goal to become an esteemed ninja and village leader. Many aesthetics, techniques (jutsu), and values are attained from a sensei's tutelage by students through much developement and hardship.
Naruto's teammates, mentors, and especially rivals act as an important part of the saga, and have individual stories that are discovered as the saga progresses. Many things portrayed throughout Naruto are connected to Japanese mythology, culture, and historical events; these relations sometimes being very unfamiliar with Western and other foreign audiences. There are currently two parts to the saga; the first one appropriately titled as 'Naruto', the second being 'Naruto - Shippūden', a two-and-a-half-year time-lapse, which is still being continued.
The viewers age starts at a decently younger age compared to much shounen anime (which is usually aired on Adult Swim), and is probably somewhere around 7 to 13+.
The anime has become very much exaggerated as the years of it's growing exploitation have increased, and has lost much quality and originality due to the 'immediately-jump-to-a-conclusion' bastard...
