Today i just fall into argument with one of my collegue about which is the best movie of Sharukh khan. This guy was uncessarily talking very high of Kabhi Alvida na Kehna while i remain adament of DDLJ. Then i thought let me gather the public opinion and then give him a fitting reply. Do tell me which movie you think is best of Sharukh and why.
