I understand that the contrast between the grieving husband and father and the family and friends superficiality is part of what makes the movie compelling. I do feel that some of the dialogue was flat and the dark comedy might have been better if the extent of the loss was not so huge. Perhaps if only the wife had died? So in the end it felt as if the supporting family and friends were way too self centred given the heaviness of the grief that should have been there.
