Not just black, but a multi coloured comedy. Pure Coens' freakish, over the top, off balanced and in your face humour that never fails to entertain, despite it does not attain the hilarity of their best works.
The casting couldn't be better; Pitt, Clooney, Malkovich, Richard Jenkins, JK Simmons and Frances McDormand all come up with charismatic performances.
It's witty, fun, absurd, violent. Brad Pitt and Frances McDormand are both hilarious, However I do think that this is not as good as "Fargo", the Coen's more successful black comedy, because there's no one in the movie with whom you can actually relate or root for, since they're all pretty much a bunch of crazy people. It's a nice movie, fun to watch, but not memorable.
It's hard to describe this, is it a thriller? a comedy? it doesn't matter, it's entertaining. It may be not Coen's most significant work, but the cast is full A-list and you don't see all this big names together everywhere.
A huge letdown when I saw it upon its release. It's still not very funny, and unlike other Coen brothers there is nothing else in the film to prop it up. It has a few moments, but not much beyond that.
