This is a kind of movie which you will find a little different from other Bollywood movies and it is made on a issue which has never been discussed publicly , shown before in a movie and talked about in media.
It is ultimately about the increasing influence of English language on our education system right from when a person starts his/her pre school ie nursery admission. The parents of the kid in this movie had to go through many problems for the admission of their child in a reputed Private school because the kids father didn't know proper English.
The acting of all the actors is very good especially Irfan khan. As always he was awesome and suitable in the character he played.
The music is ordinary nothing great.
If you like movies on social issues but a little bollywood style ie overdramatic sometimes then Hindi medium is for you.
