Part 1 showed the audience that no matter who you are, you can still succeed.
Part 2 showed us that what pt1 showed us was in fact a lie and you have to be someone who is born special in order to get anywhere in life.
kind of hard. part 1 was retarded and annoying...part 2 naruto is far less humorous and exciting...i cant choose. but i like naruto overall (except for his love for sasuke)
