Usually playing the 'guard' isn't really all that fun to do.

As an example I probably could write for hours about why I think Superman sucks and Batman rocks, but in the end it's mainly just a matter of taste, setting and character.

I think a rebelling good guy with a somewhat dodgy personality or bad image is way cooler than someone like Superman... Perhaps the person escaping from being arrested hasn't really done anything illegal, but was set-up... things like that. I'm thinking of movies like Chronicles of Riddick, Batman, Hitman , Transporter and so on where the characters were more like anti-heroes.

Cheers
