Sandesham is not a formula film. You cannot classify it as just tragedy or comedy. A mix of some, breaks some grounds but mostly is a family movie, if you must put a sticker on it.
A retired railway employee returns to retirement in his native village in Kerala. His caring wife and daughter are the only white sheep in the family. The three sons are wayward and sideward. The eldest two, played by Jairam and Sreenivasan are into politics and in opposing parties. Like their father, played by Thilakan, says, 'The sons maybe in politics but without any use to home or to the hometown.'
A good story is which uses cliches to its advantages and yet makes it memorable enough to be enjoyed as an original. Sandesham movie is such. It has all the cliches of a complete family with scaffolding support of good neighbours (played by Oduvil Unnikrishnan) and with some jigsaw puzzle pieces ,which is our version of right vs wrong vs tradition, left to be put together by the viewers. Also the comic bits are by Siddique and Oduvil with their queer and charming personalities respectively.
Watch Sandesham to understand Kerala family nuances against the backdrop of the reality of Kerala politics. Also get some gardening and soil lessons from Siddique. (has to be my fav character in this) A very apt title.
