Usually subsequent part of a original movie have a hard time beating the expectations. More often you see "return" movies rehashing the formula of the original movie. Not this one.
One of the very few movie, where you enjoy the second part(return) more than the first original movie. TWMR, does not follow the path of the first installment.
What works for this movie: Script, Class A acting, Direction, Dialogues and Casting.
While Kangana steals the show, applause goes out to Madhavan. The dude plays his part brilliantly, keeping dramatics in check, he gives credence to his role.
lastly, the screenplay and dialogues did manage to camouflage some obvious flaws in the script.
Great entertaining movie.
