This one is a different movie with cinematic excellence. You have to enter with no expectations and it is a kind of diary.There is no climax...no stunts and it just moves and grabs your attention.
I won’t call it as mainstream cinema.This one is for the people who can praise experiments and take a bite out of that one. Basically I agree with the review on CNN IBN by Rajeev Masand.
You will find mixed reactions on this ...because people are not ready to accept a movie without any climax, songs, masti and fun. Spending very high on tickets will disappoint you.
