Without any doubt, concept was good but got spoiled when creative team develop character as being fan of actor. Main conflict in this film is that senior is not ready to say sorry to his fan without any reason, just for his arrogance sake but he don't mind to butter extremely rich person just for money sake. Fan also crosses his limit to push him to say sorry. This conflict and characterization makes both senior and junior gray. You can't relate or feel sympathy with any one. First ten minutes are just collage of archive footage of senior and junior imitating him. Which is too much but after watching the film you feel like it was best part. Film starts with some realistic note, establishing junior a very common man but when Police starts chasing him, super man emerges out within him. All chasing sequences are like superman vs spider man. Audience had been taken for so granted that they can come up with so lame and stale scenes of imposture senior by junior. Height of lameness is when senior security guard and even wife can't recognize the junior, even after so much visible age difference between them and after being aware that junior can try to intrude. Makers think that senior chasing junior will look astonishing on screen so they idiotically removed the fact that professional Police exists in India and always can do many folds better job than senior in real life but after all senior tries to retaliate to junior in his style. One shot is subtle and good when junior burns his senior poster with match box, which has cover of senior. First half is slow but second half in just unbearable. In climax senior preaches and try to motivate junior but still not ready to say sorry!!!? Its just wrenching the character. Makers were aware of final product so they try to lure audience with that promotional song which is not in movie, even in end credits, so we miss at least one relief. Performance wise Shah Rukh Khan as junior Gaurav is very good, yes prosthetic makeup supported him but his expressions was perfect for the character.
