I really liked this movie. I don't understand the negativity around it. Please do not watch Imtiaz Ali movie based on what others think. People laughed at Tamasha too saying it was boring when it was released, but now they admire it. Indian audience are addicted to the idea of fictional, larger than life characters, Imtiaz Ali will make you walk across reality and help you hear your inner voice. Certainly not for the people who dig for sugary love stories.
Love Aaj kal is a decent watch. If you understand then you'll love it. It's very simple and relatable. It's about something which happens to most of the people.
