The movie is about sentiments and emotion. Sure you can say patriotism and heroism as well.
If what they showed in the movie really happened, it shows that the Indian army is very poor in planning and execution and moreover very careless.
From a technical side, the background music was so loud, we can't hear the dialogs properly. GVP, please watch some action oriented Hollywood movies to see how background scores are composed or ask your uncle.
Overall, the movie is worth a watch
