The "Saw" "trilogy" comes to a rip-cut, planed and sanded ending in "Saw III" (), a movie that fills in back story and wraps up five hours or so of blood, entrails, bone splinters and albumen.

That's brain fluid, by the way -- albumen. You see some, or a makeup wizard's version of it, in "III."

Aside from that, it's more traps set by the wily, wheezing puppet-master Jigsaw for more not-quite-deserving victims, people metaphorically trapped by hatred, fear or other shortcomings. In the "Saw" movies, it's all about what sins you've committed against society or your own potential. Every manner of torture apparatus imprison folks who are given the chance to hacksaw their feet off, burn their hands with acid or "take a bullet" to pass some "test" that will win their release.

The premise is bogus to anybody with all their albumen intact. All the back-story in the world doesn't excuse a single act that Jigsaw commits.

Rated R for strong grisly violence and gore, sequences of terror and torture, nudity and language.
