A master class in parenting...The dos and don'ts, the regrets and guilt...I think every parent of a teenager should see this...My God, I am a 45-year-old man, and the end scene...I cried my eyes out...Take care of your children, take an interest in what they do, and who they hang with, and keep them away from social media...And lastly...Stephen Graham...I have never seen a man act that good using only his eyes and facial expressions...The torment of guilt in his eyes...Watch this, trust me.
