I'm a fan of the Coen brothers' work, but not of their comedies, excluding The Big Lebowski. That is such a fucking awesome film. Of course, Blood Simple, Miller's Crossing, Fargo, and No Country for Old Men were awesome too.
This film had funny parts but I'm tired of the "out of this world stupid people doing out of this world stupid things" type of humor; see Raising Arisona, The Hudsucker Proxy, the Lady Killers, and now Burn After Reading.
