Coming to Dhoom 2 - I was totally shocked with that scene. I went to watch the movie on the first day, so had no idea there was a kissing scene. When they kissed, I was like omg! What the heck! I didn't expect it from Ash or Hrithik, so I was totally shocked and disappointed. I am not saying that they did something wrong, just that french kissing scenes are not necessary - subtle intimacy is the magic of Bollywood!
(My personal opinion)
