I'm not sure where I heard about this, may have been in a book "1,000 Movies To See", or similar title. Reading the review I got intrigued and put it on my netflix queue.
Sigourney Weaver, Emile Hirsch ("Into The Wild"), Jeff Daniels, Michelle Williams (I've loved here since "Dick"), so there's a lot to like. Parts are a bit hard to watch, and it's a slowly unfolding story, but when I suggested pausing it with 10 minutes to go so as not to miss an appointment my wife said, "they can wait".
We both enjoyed it.
