One of the best script and dialog's in recent Tamil movies. Vijay performed very well. Hats off to ARM sir and BGM is mass.Samantha is cute as usual.Neil Nitin Mukesh was perfect for his role.The message which was spoken in the movie is well conveyed and it will reach every corner of India. The dialog in the climax is class, Vijay delivered it in a very good manner. Dialogues in many scenes were too good.Only negative thing i feel that is the song placement.You can't compare Thuppakki with Kaththi, Thuppakki is an action thriller movie and Kaththi is an emotional social message movie. Overall the film is a blockbuster and a must watch movie.
