I watch KBC whenever time permits and I must say that Shahrukh has brought a new zest to the show. His friendliness on the show has made the participant more at ease. Not that he is better than Amitabh Bachchan but each has his own style.
We should always give credit where its due. When Amitabh started the show it was a novelty and that's why the show enjoyed huge popularity. The second phase with him saw TRPs falling down. By the time Shahrukh replaced Bachchan the show had nothing new to offer except the questions. And so, like his movies, KBC too relied solely on the Shahrukh factor. So far he has done justice to the show. His boyish charm has certainly impressed my wife who is no SRK fan. For me that is something!
