Children resort to addiction to something if they are facing problems in communicating with their family and friends. Probably your son is trying to distract his mind and is trying to run away from a problem he is facing. Speak to him gently and handle him carefully. Try to get out of his mind what his problem his. Be very gentle when you are talking to him. Figure out if he has any other hobbies, especially outdoor games. Try and get him involved in outdoor activities and I am quite sure he will give up his movies addiction soon. Guys, what do you think?
