Not a great trailer, but gets the job done. For one, I don't really like the "Day After Tomorrow" vibe at the start of this thing. McCarthy spent about a sentence dealing with the whys and wherefores of the end of civilization, but the trailer makes those concerns seem paramount. Comes off looking cheap and over-CG'd. The delay in getting this into theaters also worries me a bit. But there are enough hints that the dread and terror and hope McCarthy conjured so effortlessly in the novel made it into the movie that I'm excited about this one.
