It was - you know - quite funny, quite watchable. I laughed out loud one or two times; I wasn't bored. It was surprisingly sad/violent in one or two places (which I can't really explain without ruining the impact). Each character misunderstands, and only the god's-eye of the viewer pieces the story together, which is opaque to all its protagonists. I think what it reminds me of most is The Man Who Wasn't There. It revolves around Frances McDormand, it's packed with really good performances*, it's quite melancholic, and it doesn't add up to all that much overall. Worth going to see if you fancy a grown-up cynical comedy, but not awesome.
* Very actorly: Clooney, Swinton, Malkovich, Brad Pitt and Richard Jenkins.
