Such an overrated movie

I wonder how this movie became a blockbuster. The story is nothing great and we have witnessed this type of love story several times before in Woh Lamhe and many other movies where a boyfriend or a girlfriend tries to heal his or her alcoholic girlfriend/boyfriend but fails. There is not enough romantic scenes between Aditya Roy Kapur and Shraddha Kapoor apart from a love making scene. Otherwise, the hero here is constantly drinking, getting angry and fighting with people around him and even with his girlfriend. We never get to see the hero's father who just speaks to his son over the phone. If this movie becomes a blockbuster at the BO, I dread the fate of many upcoming movies with good stories at the BO.
