1. Good work by the writers (both story and screenplay, hope both are different, don't know exactly). Carefully chosen words (Ishra conversation after Ishita seeing report). Enjoyed the beauty of the language.
2. Nice direction and good technical support.
3. Last but certainly not the least, the performance of the actors. Both Div and KP portrayed very nicely. Simply superb.
Real question: Are KP and DT have not acted in any north Indian language movies? If not, I really wonder.
Hope good chances for them in tamil movies as both have a very good plus point (both unaware of Tamil language).
But I didn't like the initial 8 min or so (dancer part). I am leaving it because, once in a while not to blame CV's.
