I watched Saw IV!! It was so good! I would even say this is the best one out of the other four of them. The first two are just extremely bloody cruel, but without any stories. The third one was as well cruel but there was a strong story behind to support the whole movie. I remember I enjoyed it so much. BUT there is nothing you can compare the Saw IV with the Saw III. It tells you all about, where did Jigsaw pick up all of his wickedness. And of course, Saw IV is still full of the saw series’ signature cruel violent scenes. It gives me a feeling of watching a psychological documentary rather than just a movie. It gives us an insight look of what could possibly turn a typical man into a crazy bloody wicked sicko. I love this movie I don’t think it would disappoint any one of you, either. It is definitely not a bad idea at all to go to the cinema and check this movie out.
