Excellent dialogue

I loved the dialogue for this film although most of the time it sounded as though they were improvising the scenes and reacting off each others lines. It seemed like a reality tv show, so great & natural. Vivek Oberoi was excellent in this film and worked very well with Rani Mukerjee. They are both down-to-earth people in real life and get along brilliantly which reflected well on screen.

I enjoyed this film very much. I laughed loudly at all the funny lines ("sambhalke...yeh computer hain aapke dadaji ki typewriter nahin") and smiled at the romantic ones.
What do you think of the dialogue?
