This is a never ending story. Last time i thought SAW was already over. I thought the main character is already dead and the story is over. In terms of marketing terms, they pushed the product cycle back from Decline to Growth. They are not in the introduction stage because people already know about SAW.
The demand for SAW has increased due to the increase in benefits in the new SAW 3D movie. Well, obviously, it is 3D. But in the story (plot line), the murder kills people in the public now. It is also considered to be a benefit, because it increases the excitement which is the feeling people expect in a horror movie.
Now, we are going to see another wave of SAW , this coming Halloween
