Look first it's a docudrama, which means everyone has to look and act like a real life Indian cricketer. This is a technically well made movie. You see some actual real cricket action not just patched up shots of someone bowling and someone batting. They have tried to recreate the same play sequences as much as possible. So the ball seams or spins or swings as was seen on the live telecast.
The West Indian actors as cricketers were good and they plugged in quite well to the narrative. Well they got Malcolm Marshall's son to play as him no wonder it looked very realistic.
Yes there are the usual cliches and some history lessons and a tiny bit of melodrama you would expect in any Bollywood movie but it keeps you entertained.
If you hate cricket don't bother as that's what 90% of the movie is about. There aren't any silly song sequences and traditional melodramas.
Jiiva as Srikanth and Ranveer as Kapil Dev are simply great.
All in all an entertaining fare and this should serve as an impetus for other sports movies as well.
