What was fresh and original horror film film seems dated and stale now as the series continue to decline in story and credibility. The story involves the now deceased Jigsaw and his motives are done in flashbacks then flashforward to his latest set pieces he planned up until his death. The ending what used to be surprisingly was laughable. The interesting thing about the Saw films is it gave D list actors(Donnie Walhberg, Dina Meyer)and forgotten stars(Betsy Russell of 80's T&A films.)a chance to appear in a box office hit. Unfortunately we have a part 5 to slug through, hopefully it will be an improvement-one can only hope.
