The movie is really worth watching from a Director's point of view.
To the point let's accept the fact that every bollywood movies has no or similar story lines, it's the Director who gives a different shape, makes the audience to stay tuned and watch till the end.
In terms of acting, everyone has played their part with full honesty. Kunal Khemu is brilliant actor but has under rated so far, though he used the space correctly this time also.
The editing and script / scene writing is really upto the mark. At once you feel why a particular scene is there in the movie, but then it does connect to another important scene and you then give full credit to the scene.
Songs are good, but the title song is taken as baseline for few scenes and it makes greater impact.
End of movie has twist but if you accept twist of "War" movie then you should accept end of this movie.
Overall, you can definitely spend your time to watch this movie.
