I found the movie very entertaining as it had plenty of elements that appealed to me. It is set in the background of artists' lives and starts off with a popular folk song and multiple song gatherings throughout the movie with a distinct folk rhythm to them. Also, it gives a convincing presentation of the closeness in the group.
Sreenivasan has acted really well and the attitude of the protagonist that he plays more or less shadows well with Sreenivasan's own line of open unassuming philosophies. His son Vineeth Sreenivasan has sung the song "Sasipaattu" which is an easy entertaining song as well.
Characterizations have been very convincing. Sasi has his own lifestyle but has the maturity of his age and is very considerate to everyone in his group. There is the husband wife pair and Sasi openly saying that he loves the wife and asks the husband to let her go. Such openness that could have sounded drastic was captured smoothly.
The movie shows a lot about real life. The person who means the world to you and who you gave everything to and for whom you lost everything can be in a situation that they cannot even acknowledge you and yet that is the reality and that needs to be accepted.
There are many such stark sharp realities of everyday life that the movie brings up throughout. The movie also takes stances against various social evils pretty boldly and directly.
There is also a more philosophical thread to the movie about attachment and brings out the futility of attachment again pretty convincingly. Life is not all that lofty. Stay grounded.
Of course, the movie is not for everyone. It is not made to conform to an expectation matrix. It definitely has a soul and life of it's own and has something to say.
