If you do see it in IMAX, when Rorschach flips the smiley into the Comedian's grave I bet you'll be able to feel that >ting< in the roots of your teeth.
I like the >BOOM< when the blood hits the badge. THIS IS AN IMPORTANT IMAGE! Yeah, I'm betting even my mum knows the cover to that comic, thanks.
I guess they changed the ending. That really sucks.
