The one aspect about Mani Ratnam which never changes is his capability to narrate any story within just 3 Minutes. He usually uses some selective words during the narration, alike the sharp oneliners in his movies.
Mani Ratnam's narration for 'Ok Bangaram' went like this - "Two characters… there is a love between them and they have a condition… the film is about their chemistry and state of mind".
Even if the listener is Ram Charan or Dulquer Salmaan, There willn't be any change and Mani follows this rule strictly. Even the Veteran who have immense experience believe a story which can't be narrated in 3 minutes isn't at all a story.
'Ok Bangaram' is a beautiful love story and the fact that its the favourite genre of Mani Ratnam is making this film a hot cake.
