As far as the story-line is concerned - this biopic feels like a MS Dhoni promotion. It just shows the positives of his life - leaves out all the controversies. In short - it feels like a biopic written by a MS Dhoni fan.
But, at the same time, the acting and direction are amazing. The cricket scenes feel real and you can feel the emotions. Yet, it does suffer due to bad editing. Some scenes are stretched too long, and the songs just drag the movie to the 3hr length.
Overall - it deserves 6/10 - for acting, direction, and lastly, for MS Dhoni!
