I don't care if the movie is remake of a South Indian masterpiece. I never watched that South Indian movie. So I can't relate this movie with that original. This movie, however, I found very good overall, but it's ending failed to deliver a good impact. Maybe because the protagonist here was a woman instead of a man. And after what she went through the entire movie such a passive ending with mostly negativity for her made it extremely unsatisfactory. The movie till the ending was a extremely good, however. And I'm really impressed by how Sonakshi Senha played her role. Anurag Kashyap also did extremely well, and so did the rest of the cast. Action sequences and choreography was also marvelous. If the ending was handled properly this could have become a masterpiece, and one of the best Indian movie involving a female protagonist. Sadly, the ending ruined the movie for which I cannot rate it too highly.
