I enjoyed watching the film, but I struggle with so little attention that was given to Walt and Ann. They raised Hunter to the mature and well-behaved boy he was, but you don't see even a little acknowledgment from Travis and Jane or even a scene showing them in the third act. To me that seems unfair.
Other than this, the emotional engagemen of the film is quite high, keeps you wondering what could happen, nervous and hopefull at the same time.
