I saw all the 7 parts of saw series in a single week for the first time after I heard about the movie. The first part of the movie is the best among all. The climax of the movie is such that no one would have expected it. Without this part the entire series of films would not be worth to watch. The character of John Kramer, the Jigsaw Killer is a fantastically made character which resembles a little like The Joker in Dark Knight Series. The film emphasises more on the thought What ever mistakes done must be Punished or else it continues.
