the idea of friendship and protecting precious things is a standard shonen theme, which is why i regarded hard work as the main theme.

as far as rock lee goes, he fails at every major battle, and its always made him look pitiful in my eyes, someone who works so hard getting overpowered in the. its the same situation with deidara and sasuke. sure everyones working hard in the series, but at least once id like to see a kekkei genkai user lose to someone beside a jinchuuriki
