…what may be the most spectacularly depressing movie of all time!

Really.

Roland Emmerich — who obliterated much of the world in “Independence Day,” and then went back to do it again with “The Day After Tomorrow” — turns his dark imagination toward the End of Days and post-9/11 angst with something called “2012.” The trailer, below, is a stunner. But does anyone really want to spend two hours with this?
