I really liked the movie. If you've get in the shoes of Ayan you can actually see why he acts like that! A girl kissed you, understood you, was your best friend, helped you through breakup, when you showed her feelings, she told you love is nothing but weakness, you went on trips throughout the world, but when she saw her first love/ex, she flip-flopped on her words and married her! Leaving you alone and lonely.
But if you get in Alizeh's shoes, you can feel her too! Your first love cheated, all bfs you had or the guys your father arranged for you cheated on you! You got no one but that one guy best friend who you don't wanna lose! But you're scared of relationships! Now your first love is asking for forgiveness, he's been waiting for you for years! And you actually were never attracted to bestfriend in the way he was to you, and you clarified it multiple times and he even said he understands! Now you get married he is still doing the same. You love him as a friend but he can't understand! You try to contact him but he doesn't answer in any way! You can't find him to clarify and keep him close again!
A top notch acting by every single actor! Ranbir, Anushka, Aishwarya, Fawad, Imran Abbas, Lisa Hydon, SRK, Aliya!
