I don't really see a problem here. Sure, if you expect every detail of a sci-fi/fantasy movie to adhere to one's notion of "realism", then Cloverfield's opening DoD card is distracting. But within the context of the film it does a very simple job in an efficient way. Just dropping in the words "the area formerly known as Central Park" immediately sets the tone of what's to follow and basically forewarns us that Central Park's shit is going to get fucked up.

I like to extend some lateral leeway regarding such "errors" into the film's fictional universe. Perhaps the DoD employee decided to get a little bit creative when typing out a description of the footage on the video tape. Also, why are people complaining about the typography/design of the card itself? Does the DoD have someone like The Designer's Republic on staff to ensure all internal memos, labels and correspondence are conveyed via some post-modern design ethic to appease hyper-critical design students who happen to gain access to such material?

Sometimes a movie is just a movie.
