Well... Sin City and 300 aren't really Supe Hero movies... just based on Graphic novels... seeing as you're posting them though:

300

Love that film!

X2 was really good, so was the first Spider man, nothing beats the first 2 Batman films and the newest was pretty good.

Not seen the new super man, Daredevil was alright imo... what about 'batman and robin'? :P
