Indeed it did take a turn.
Burn After Reading had it's few moments of comedy. Overall I felt the movie lacked the coherence it needed. If the movie was intended to be sad, or make me feel anything other than annoyance then it failed. I didn't care about the characters. I cared more about what the actors where doing as the characters rather than what happened to the characters.
They should have called it "Burn After Watching", ha ha ha (I'm sure the Coen brothers have heard that line thousands of times)
Movie was ridiculous.
