As mentioned no need to compare with SAW , but few scenes could have changed to Indian culture eg: fight between doctor and his wife or the doctor's baby sleeping alone , calling CBI police as "officer "etc. This movie too didn't reveal how killing the police is justified ? Lack of technicality and story focussed only on delivering Tamil version of the movie . lastly giving the background of the killer in first part broke the suspense of the movie SAW had .overall the movie is poorly executed .
