The "Saw" trilogy are low budget independent movies that have become Halloween blockbusters hit since 2004. The original film costarred Monica Potter, Carey Elwes and Danny Glover and these actors did return in "Saw II" and "Saw III." Draw your own conclusions. Dina Meyer (http://www.dinameyer.com/) and Tobin Bell http://www.officialtobinbell.com/ do manage to star in the complete trilogy.
The modus operandi of Jigsaw provides the classic moral dilemma of a good fairy tale. Jigsaw is a terminal patient and he does not like it that people take life for granted. Therefore he tries to keep these people a lesson by torturing them. Jigsaw frequently makes his victim chose between a rock and a hard place, much like Howie Mandel's game show on the NBC network.
While the ideas create good drama, the cinematic presentation is messy and suffers from too many flashcuts. "Saw III" runs out of story ideas and merely repeats scenes from the original "Saw." Six hours of S & M drama just numbs the viewer.
Sadly, "Saw III" has made more money in 72 hours than Clint Eastwood's excellent "Flags of our Fathers." It is interesting how ticket buyers can accept the fake, but sadistic, violence of a "Saw" movie - but are unwilling to face the sacrifices of the "Flags of our Fathers." Perhaps this marketing sampling is the ultimate horror that we face this Halloween.
