call me a prick, but I don't think there's such a thing as a "great silent protagonist" if they were so great, they'd have the ability to tell people to piss off when they don't feel like doing ***** work like "Hey, go flip that switch on the other side of the room because I don't want to." I'm an average guy and I could say "No, your legs aren't broken, jerk-face."
edit/addendum: or better yet, in dead space when Kendra calls you and she's all "oh god, what was that?!" Issac just keeps walking instead of saying "It's probably one of the five million things I've seen and killed, what the hell are YOU doing to make this situation better?!"
