Movie Ok Jaanu is not so ok as a movie. The movie is a typical indian romantic movie which is not so impressive. It is a copy of a tamil movie.
Aditya Roy Kapoor and shraddha kapoor came back together after Aashiqui 2 which was a success but this one was not imoressive. Their performance however was good.
Direction of the movie is poor. The original tamil movie was much better than this one.
Music was the only good thing about the movie. A.R Rahman gave music for this one and it was expected to be good.
Overall, a very average movie, nothing impressive.
