On the brighter side, there was some great gore. The effects team relied on "real" effects rather than CGI, which I always give kudos for. There was also a pretty tense scene in which two characters were in one of Jigsaw's traps and they were each attached to a breathing device and a device around their chests that would slowly crush them if they breathed. It was a test to see which character was more physically fit and therefore more "fit to survive." The scene definitely had me holding my breath.
The main pitfall of Saw VI, however, is the blatantly obvious attempt at commentary on the "evils of the insurance companies." Really? I mean, I'm watching a Saw movie, not a film by Michael Moore. Keep your politics out of my Saw movie, Mr. Director!
