In simple words this is really a great movie and infact a must watch movie to all the Indian cricket fans or even if you are not a cricket lover then also I would recommend to watch because it's inspirational.
Technically the first half was much better than the second, a lot about the childhood and the upbringing of ms dhoni was portrayed very beautifully.
All the characters in the movie were awesome specially sushant which I thought was was exceptional and had pretty much mirrored msd.
Overall this one is a no brainer, everyone should go a watch it.
