For those who are interested in the mythos surrounding the Jorasanko Tagore family, this film is definitely recommended. Yes, it has a haphazard way of depicting the sequence of events, and of course not everything shown in the film is accurate from a historic point of view, but very few concrete facts are known about the actual incident on which it is based. At the time when this happened, the Tagores were the most talked about family in Calcutta (it was called Calcutta back then), and they did everything in their power to keep it hushed.
In spite of this, the movie has some great performances, particularly by Ms Sen and by Kaushik, who plays her husband. It's a moving tale of how a young girl is married into one of the most immensely wealthy and influential families in Bengal, and how she has to adapt to a new and somewhat orthodox environment, even making a lifelong friend along the way.
The background score is impeccable, with Ustad Amjad Ali Khan working his sarod magic, and there are several great songs, too. Even with the inaccuracies, I felt that the essence of the period and the Tagore family environment has been depicted very skillfully, and makes for a good watch. The duration of the film is short by Indian standards, and the pace is well maintained.
The bottomline: do not watch this with expectations of documentary level accuracy, rather enjoy it like a legend or a campfire story. You won't be disappointed if you really are interested in anecdotes about the Calcutta of old.
