Of course, this isn't a Coen brothers film, but it does have a strong connection to their films with Ethan Coen contributing to the script (but not producing) and with the Coen's storyboard artist J. Todd Anderson directing and also co-writing. As to be expected, it's not as good as a full Coen brothers effort, but worth a look for anyone who is a fan of the Coens (as I am).
That said, it's not a great movie. It does have a pretty funny central concept, but to me, it never seemed to completely get off the ground. J. Todd Anderson directs the film in a similar style to Joel Coen, but he isn't near as good as writing funny dialog. There is some stuff here that people with a weird sense of humor (like me) will appreciate, but mostly the film is meandering and pointless.
Definately not on the same level as the Coen brothers' classics, but worth seeing for anyone who likes the Coens, or weird comedies in general.
