In a short note, simply superb..
Introducing the main issue in the film in the first 10 mins of the story is a great move. It engaged the people to the point. Later, the director took his space to establish the hero character and we didn't feel lag as we already started feeling the pain of the characters.
The actors did a phenomenal job, especially all the tribal characters did a wonderful job, the actors lived in the tribal couple charcters and as always Suriya lived in his character.
The lyrics are also added asset to the story. Time to time background score with lyrics created depth and created that emotional feel in us.
