I believe Naruto shows us many elements of real life. Even re-reading and re-watching it in my 30's I believe it has life lessons that would make the world a better place and myself a better person. Having guts, valuing friendship, banning hatred. I believe some of these are taught in the story in a very strong way.
Story:
Especially when re-watching I enjoyed the introduction of characters, jutsu and other elements of the narotoverse. To me, everything makes sense and the build-up towards emotional developments, clashes between friends and incremental strength of characters is well thought out. All things introduced, later appear to have been mentioned for a reason. Not in a big announcement kind of way, but very distinctive.
Art:
Maybe not all of the artwork has the same amount of detail and attention. That being said, some of the scenes featuring hand-to-hand combat are magnificent. For me the artwork is good enough to have some elements in my child's bedroom. Can't be that bad then aye?
Sound:
No discussion. Intro and outro are continuously good. Changing every 20 episodes or so. But the real winner here is the beautifully matching and emotional music during various scenes. I know they've pushed me over the edge of having some tears every now and then. Simply beautiful.
Character:
Some characters annoy me. However, Naruto gives you many many options to choose your favourite character from. In addition almost all of them get enough screentime and a fair share of character development. Some, I simply like more than others (Naruto, Sasuke, Itachi, Shikamaru, Jiraya, Kakashi). Some (Sakura, Ino, Choji, Shino) are a bit shallow. Nevertheless the connection between most of the characters and the briliant development (and backstory) of some of them made me connect with the whole story.
Enjoyment:
Both the manga and the anime I enjoyed very much. I personally could not get enough of Naruto, so I even enjoyed the filler episodes.
