I was quite surprised that the Coen's struck back so quickly, after the bloody fantastic No Country For Old Men (I can't understand why some people abhor that film, I really can't). No wonder then, that its good - but nothing more - the Coen's overall talent sees them through to producing a solid (and sometimes surprisingly dark) comedy caper ... but the sense of under-cooking drops the film right there, on the better side of the middle lane.
The comedy is good, but not guffaw-worthy. The plot is good, but not gripping. It's the case with the whole film, but for a decent viewing time without investing too much effort, it really is worthwhile - particularly for Coen brothers fans.
