In short - this movie has nothing to treasure.
The songs are good. Padmapriya has acted well in her role. As a director Cheran has done some reasonable work giving importance to even the simplest thing on the screen but still the movie lacks its lifeline - a good story and proper screenplay.
The hero writes a letter to the heroine. Heroine reads that letter. She then write a reply to the hero. This time hero reads the contents of this reply to the audience. Then he writes a reply for that reply letter and this repeates in the while(true) loop :-(
Director Cheran would have wanted to recreate a hit like Autograph, but this movie comes nowhere close to that movie.
