Is it necessary make a sequel of a hit movie?
I say .no
Sarkar is a popular and good movie, than it is not necessary to make its sequel. But director made it because he want to make benefits of past hit movies name.
There are unnecessary dailogs in movie. If you like to watch only dailoge than you can go to watch Sarkar 3.
I respect amithabh bacchan. He did good work in this movie. But we need another things too in a movie.
But it will disappoint you if you are expecting pervious movie level in this movie.
