Okay, it is upbeat. It is a fast-paced love story, almost with like a "Vrooom" label on it. The small duration is definitely an add-on here. The chemistry between Aditya and Shraddha was never a doubt, as they hit off their career with a successful romantic film. It also struck my mind that Aditya has always been consistent with his performances but Shraddha is very unpredictable. Her work in her last few films was a disaster and the complete opposite in the current one. Moving on, A. R. Rahman rocked the music bit and Naseeruddin Shah and Leela Samson also do their parts quite superbly. It is based on a Tamil film by Mani Ratnam [Ok Kadhal Kanmani] who also gives the contribution of screenplay, story(was originally by him) and production in Ok Jaanu. The film’s high point here is one of the approaches of modern relationships. Yet, it doesn’t quite fill the bill for me. 3/5
