Loved this movie. It has kind of a desolate/lonely feeling, but it's also a good reminder of how differently we all live our lives, how quickly things can change and how life is what we make of it. It was a lot to take in at 2am, but insomnia can feel kind of lonely so it was fitting.
Also Frances McDormand was amazing in this and there are real people from this lifestyle in it and I felt they portrayed them with respect. If you were fascinated by Into the Wild you might like this too.
