I have watched this movie trailor, it was awsome. And the trailor forced me to watch this movie, because it was too good.
The plot is very new. The idea is very good.
Hrithik Roshan and Yami Gautam, both are superb and have done a great job. Their performance is very good, very impressive and very convincing. Both looks very cute.
The sound tracks are not good. I mean some of them are remake of old famous songs. But it is quite good.
Cinematography is also very good.
I would suggest you to watch it. I'm sure you will definately like it.
