This is a marvellous black comedy. The whole point of the
movie is that there is no point, and that your life can turn to shit, and you
will never know why, no matter how many authorities you appeal to for an
explanation. It's the atheist Book of Job. So if you think you could watch a
film that tells you that a blind, uncaring universe could easily randomly
select you for sufficient misfortune to ruin your life, I highly recommend it.
The Coen Brothers are on fire right now.
