Nowadays movies are not a big hit naturally. They are promoted for months and years, promos are released months before the release of movie Actors and Actresses roam all around to make their personal impression in the audience, the story and songs is leaked (released) before the release of movie and even then a movie lasts for hadly than 2-3 weeks in a cinema hall.
What's special about that figure of 100 Crores when movies nowadays are released in Multiplexes where the tickets cost in thousands.. In a few years, a rise in the cost of tickets will help a movie make a business of 500 crores and still the movie won't be called a big hit..
I have just seen this movie. It is more of a love story between Indian Spy & Paki Spy. Except few moments, movie is slow paced. Salman Fans will like it.
