Beginning is excellent as Kareena's superb dialogues literally will lead to a laughing riot. Her natural acting blended with perfect comic timing is a huge plus for the movie. Although Shahid Kapoor tried to emulate the depressed Aditya Kashyap's role well it becomes a bit too exaggerated in the later part of the movie.
The second half is too lengthy and has a lot of loopholes. Too much focus on Geet & Anshuman's relationship makes the story a tad boring. However, the liplock between Geet and Aditya in the end steals the show. I thoroughly enjoyed the excellent comedy that was portrayed by all the characters precisely.
Overall, a fine touch of romantic comedy feel is what you get after watching this movie.
