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.
Big Lebowski is so great because of the characters, the plot doesn't matter at all, in this one only McDormand, Malkovich and especially Pitt characters are good enough to make the movie a good comedy. 3.5 / 5.
A twisted tale, that is funny, sad, enthralling to the finish with some wonderful performances from John Malkovich and Brad Pitt. This can be held high amongst Coen classics such as Fargo and The Big Lebowski. 8/10
