Mumbai, Sep 17: Barfi boy Ranbir may be delighting the audience with his performance with critics among his legion of admirers, but Papa Rishi Kapoor is not satisfied. Rishi Kapoor, who created a rage among the teens in Seventies with Raj Kapoor's film Bobby, feels that there are several flaws in his son's histrionics. Though, Papa Rishi feels proud of Ranbir's choice of picking challenging roles but as an actor he doesn't like his flicks and finds numerous flaws in it.Rishi Kapoor never interfered in Ranbir's decisions and always gave him freedom to do whatever he wants.Earlier there were rumors about aminor conflict between the father-son duo but it soon came to an end when Papa Rishi fell ill which brought them closer. Later at an awards event, the father-son duo shook their legs together, sharing a stage for the first time ever.Though Ranbir has proved his mettle with the two consecutive back-to-back hits “Rockstar” and “Barfi!”, yet he may have to look into concerns raised by his father.
