Well, this movie is worth watching. It really shows the real truth of Sanjay Dutt. If people think that this movie is portraying Sanjay Dutt a good person only and there is nothing else, then I would say, no, many times this movie also shows Sanju as guilty and wrong.
There are many incidents where Sanju takes inspiration from songs of old movies which his father used to sing, to motivate Sanju. I personally loved these incidents more because I personally also applied these things in my life and took benefits out of these quotes.
Overall this movie is worth watching. Ranbir portraid the character with honesty. Pares Rawat, Vickery kaushal, Anushka and Diya Mirza all performed very well and looking real on screen all the time.
