The movie "Grandmother" offers us all a look at a very serious issue which Josh does not tackle here as well as the notions of love and family, which he does.
What does it mean to have someone in our lives like Lily Tomlin's Elle Reid? She is a woman whom her family can go to when they need help. She is fiercely protective and while she may be a little exuberant or uncouth, she has her loved ones' best interests at heart.
