You gotta be kidding here. First, the only people who are likely to have a clue about Watchmen ARE the fanboys. Giving the story away with a cheesy voiceover NINE MONTHS before it comes out would achieve nothing. I think Zack Snyder played his cards perfectly here. Those of us familiar with Watchmen know what's going on, and we don't need to be spoonfed the story. This trailer is exactly what is needed to get the rest of the world wondering and talking about it.
