I see these solely based on tradition. They offer no new insight to anything and are getting dumber and dumber. The Jigsaw killer (who died in part III, I think) somehow manages to come back alive through worthless flashbacks that set-up a whole new “plot”. It is never really explained why an FBI detective has taken over for Jigsaw, but it doesn’t really matter, I suppose. People come to these for one reason: to see if the filmmakers have thought of new, interesting ways to kill people. The acting and the plot wholes are so bad in this franchise, that you won’t even care who dies, or how they are killed. But it is Halloween, and if it’s Halloween, it must be Saw.
Judging by the end of this one, this franchise may keep going for a while. The films usually make their money back in their opening weekend grosses, so let’s guess how many of these there will be. It’s a scary thought, but five years from now, can’t you picture a Saw X? D-
