First YOU ARE A FREAKING GENIUS!! This is brilliant on so many levels and so well written and complex yet so well woven together I can not find words to describe it. That being said Normally I stay away from these (like politics and religion) don't talk about them unless you are looking for a fight but as I understand (while still just as sensitive a subject) this is coolness- not who would in a fight, and for me it is not possible to quantify and compare these two characters, they are different archtypes and thus their coolness is different and (for me) incomparable. Riddick is an anti-hero and Sparrow is a lovable rogue, they are each extremely cool but for vastly different reasons but maybe I just need more information to understand
