After Vicky Donor and Madras Café, director Shoojit Sircar has delivered yet another winner in Piku. And while it's got an emphatic thumbs up from both critics and the audience, Sircar says he's surprised by the response. Says he: "I actually didn’t expect this kind of huge response. You see, it is very different kind of film, and it felt really good when people accepted it the way we wanted. Such stories do look simple but are complex in their nature."
