im not a manga reader, but i have read the first volume of naruto when i was at a book store
it was pretty cool
i just like reading it afterwards to see the similarities and differences/ what they added in the anime and changed, thats all
i dont want to spoil myself by reading the parts that the anime havent reached yet because i would just be watchin the anime to see the animation

but, theres always that temptation

(comparison) in a sense, its like lord of the rings, people whove read it want to see how it would look like, and people whove watched the movie went out and bought the books
