Could very much be a mediocre Coens' film.
I enjoyed the film, and these Coen brothers similarities weren't without notice:
Malkovich: Burn After Reading
Billy Bob: Intolerable Cruelty, Fargo TV series, The Man Who Wasn't There, Bad Santa
Large Native American: Fargo
Michael Stuhlbarg (Derby Milton): A Serious Man
Oliver Platt: Fargo TV series
You could probably pick apart many films this way, but this one had a very Coen Bros vibe to it. Anyone agree?
Edit: Apparently several people noticed this similarity.
