Amir Khan has been mistakenly led to feel that he is a much finer actor, best among khans when it comes to acting and definitely superior than most of his contemporaries. However, even from the trailer of the movie it would become obvious that he has same facial expression - the one where he has an awkward smile on his face with his eyes wide open. He has been carrying the same expression since 3 idiots and it has now become so irritating to watch.
The movie is terrible to watch, more so if you have already seen Forest Gump. Amir clearly lacks the depth to portray his character with honesty. Despite more than two and a half hour of screen presence you don't feel connected with Amir's character.
