He did Kwon. I just can't really explain movies like Spiderman and Superman. They have not translated well to the big screen. I liked the Iron mans, Avengers, and most of the Batmans though.
Spiderman---nerdy dude who has super powers, many times out thinks or out manuevers his opponents due to acrobatics. Also, has a lot of emotional content, and deals with his conflicts with his power.
Superman----an all powerful being, that even in the cartoons has his power "dumbed down" (he doesn't go full force because he knows that he could take out basically everybody and everything). WHich also is a "moral conflict".
This doesn't really translate that well in terms of "action" (which what we want to see), because Spiderman is not as strong as the "Sinister Six" and Supes is all powerful, so the storylines must deal with their failings...sure people will go see the movies, and sure they will of course make millions, but imagine if Marvel went all out with a Wolverine movie complete with lots of blood and guts? R rating, and you can't take the kids, meaning less money.
