For thaliavar fans : karthik brings back the Rajni of yore in every frame and his mannerisms and style are worth watching. The fight scenes are also good.
For neutrals : The movie is very weak on story and screenplay. Nothing new to offer. Even drags at certain places and you begin to yawn. All the remaining actors have been wasted as they don't have memorable roles.
Another plus is the terrific music and bgm by anirudh.. Worth enjoying in theatre.
So I would say if you are a Rajni fan watch it else take a call whether you would rather spend this money some where else.
