Cheran’s approach is always different from the routine stuff, which he has proved in his earlier films like Porkaalam, Bharathi Kannamma, Paandavar Bhoomi. Here also the producer, director, scriptwriter and actor Cheran has tried to project the film differently with his own classic touches. As an actor he has played well, but as a director there is inconsistency in the screenplay. The film is bit too long and dragging. Sneha has given a brilliant performance. Though appearing in a cameo role, she is so natural and full of zeal. Mallika and Gopika are sufficient. All the characters are etched out well. Music by Bharadwaj is melodious. The four cinematographers need special mention especially the one who has captured the unusual locales of Kerala.
