Be it acting, cinematography, songs (playing at background), dialogues, genuineness (nothing felt like it has been pretended or just imposed forcefully to the movie), all of it defines this movie, why it deserves to be called a masterpiece.
Movie makers hadn't left a stone unturned in collecting the evidences, fact checking and done a thorough survey for this movie. A sincere salute to their courageous and reckless instincts for making this movie.
And yes, hats off to Adah sharma, this movie is (will be) indeed the best movie of her career.
