My only concern about Burn After Reading, the comic tone of which seems exqisite in its dry, deadpan-ness (being a smart but broad lampoon of stupid people with delusions of grandeur), is that it’ll be too fully appreciated and digested by the time in opens in mid-September. Meaning that people may go to it saying, “Yeah, yeah, we get all that, fine. But that was last summer and this is September, so what else can you show us?” I’m speaking, of course, about a very small group of online trailer-watching aficionados.
