This is probably the best bollywood movie of all time.
Within the first 120 seconds of the movie you already know whats the film about.
Within 16.18 minutes you know almost everything about Ranbir Kapoor(Barfi) like his weakness,strength,characteristics and his aim(to find a trust worthy partner).
And then before 23 minutes you also get to know why Ranbir and D'Cruz(Shrusti) love each other.
Its just brilliant and a S grade movie
