Flawed, but still very good.
Frances McDormand is one of the greatest actresses of all time. She's great in this. This film is great. It's very, very funny and feels a bit like a Cohen bros film, which is no surprise as McDormand is married to one of them. The only problem I had with it was the sudden change in personalities of a couple of characters in the third act and the fact that it seems a little too heavily oscar baited at times in terms of script / tone. But that said it easily makes the top x movies of the year list.
8/10
