It's fine. A week in the life of a bus driver who is powerfully content (numbingly so) and his wife who is powerfully ambitious (annoyingly so) is about as ordinary as it sounds. The poetry is interesting, the relationship is sweet, and this role goes a long way in displaying Adam Driver's range when contrasted with such films as Star Wars and Silence.
It's a perfectly fine movie. But if I read another review claiming it's about the "brave" decision to get out of bed and go to work every day, I'll throw up.
