What is your first impression of Raj? Grown-up Shah Rukh! At last! He was 35 when this film was released, and is playing close to his actual age. There's enough suppressed mischievous humor to keep him from being too much of a paragon. In the flashback, he does a great job of portraying the awkward student, without being at all annoying.
What is Megha's first impression of Raj? We don't get to see the very beginning, but clearly she sees him as "different", though that could be a result of their attraction for each other. But she trusts him, just as she trusts her father to accept him.
How would you describe their chemistry over the course of the film? Steady and pure. It has that "first love" aura throughout. SRK and Rai are well-matched physically, and I think she makes him a better dancer, just as Madhuri Dixit does when they are paired.
If you had a first date with Raj, would you go on a second? I did. Just a different guy. In fact, dear reader, I married him. And no, our parents did not approve.
