I was all looking forwarding to watching a brilliant mystery thriller after hearing about all the accolades and imdb rating. Alas, I know now that these can't be trusted. Out of the 2 and half hour something movie, atleast one hour can be said to be watchable and interesting, especially the main actor's initial story and the antagonist's method of killing and his backstory, these are told well. Otherwise, the plot just crumbles.

Like most tamil suspense movies the focus seems to be more on sensation than on plot. Most of the other actors (the heroine's character, doctor's character played by N Ravi and many more) it seems are there just to make the film 2 hours and more. They hardly contribute to the plot.

Like in such movies nowadays, through coincidence or by accident the clues are found one after another, plot gets unravelled and the murderer is apprehended rather than the hero or the police actually racking their brains and investigating.

Watch only if you have nothing else to do. Otherwise rewatch any of the popular Hollywood serial killer movies.
