Are we ready to accept Kriti Sanon in place of Dia Mirza for the sequel of ‘Rehnaa Hai Terre Dil Mein’?

Zara Zara is still one of my favourite song, I don't think we need a sequel of this 2001 popular film. The original star cast and the film has it's own charm and fan base. Can't they recast the original stars Dia Mirza, Saif Ali Khan and R Madhavan!
