Story, Screenplay and Direction:The story is interesting if you haven't read the novel or seen the various take-offs on it (including the recently released Strangers Hindi). But it seems predictable enough in the second half. There is a logic glitch or two, including the fact that Dr. Raja doesn't know his harasser's name
The screenplay is good in the first half. The grip slackens a little once the story gets predictable. The dialogues involve a lot of profanities and double entendre. The focus could have been kept only on the thriller quotient of the movie, or make it totally commercial with all the apt elements. It comes somewhere halfway.
The last 40 crucial minutes is not well-executed. Apart from that, the movie is watchable but only if you haven't watched the other movies with this plot (because they happen to be way better). The humor is nothing to write home about, the ladies have little to do and the one merit is the performances of the two protagonists.
