Who Watches the Watchmen?

I saw Watchmen yesterday, and for me, it is one of the best super hero flicks ever made. The fact that I had previously read the graphic novel and was familiar with the story no doubt increased my enjoyment of the film, and I'd definitely recommend reading it first (or watching the motion comic on the iTunes store). That being said, the two people I saw Watchmen with had never read the story and they both enjoyed it as well.
