I just watched this movie 2hrs ago, and I think that this is an average movie, based on friendzone and one sided love of Ranbir Kapoor playing role of Ayaan towards Anushka Sharma playing a role named Alizeh. Both of them have a rich background. Ranbir that is Ayaan in doing MBA( Mere baap ki aarzoo according to the movie) and he meets Anushka that is Alizeh in a bar, and after some intimate scenes they come to know each other and becomes close friends. While Ayaan started getting attracted towards Alizeh and falls in love with him.
Ayaan has a good voice in this movie, he sings well. After the marriage of Alizeh with Ali who is a DJ at a bar in paris and they both are college friends and love each other since their college times. After their marriage, Ayaan gets totally broken and he mets Aishwarya Rai playing Saba, they both fullfill each other needs in every way. Saba is a writer who writes Shayari. Thus from Saba Ayaan gets the lyrics of his first song. While in the end it is revealed that Alizeh is suffering from cancer and she wont live long.
The best part was the dialogue delivery by the actors in the movie. Everyone did their job well.
