This movie is doomed to fail from get-go. The characters of "Aranyer Din Ratri" were so complete in that movie, that there was hardly anything to add. With passage of time people changes, but with so many new characters around in this sequel, it was impossible to explore the surviving cast. So from the very beginning, the story does not have any focus. Just a picnic! Surely Mr. Ghosh was aware of the apparent lack of theme and so included whatever he could find such as, 9/11, CIA, KGB, family romance and melodrama, accident, not to mention the many songs. After one hour, it becomes really difficult to watch. There is no story thereafter. Last 30 minutes is director's self-indulgence to make a political statement, which was hanging around - uselessly and without proper fit - almost throughout the movie.
It's not clear why we needed Tabu for the role, though even bigger question is the very existence of the character. Tabu's role got too much time and it is not at all convincing - least of all, her philanthropy. The script itself looks confused and fussy. Too many extra characters. Hari has been reduced to a jerk. Added to that mindless recall of scene, song of the original work. I was hoping to hear whether Kaberi Basu's role is being looked after by her son, who was a child in "Din Ratri".
There is just not enough material to make a full scale movie. The result is a work without any focus.
Goutam Ghosh should try to focus on Bengali literary works for theme and story. That suits him far better. He can movie much better than this one.
