missing pieces

Rating: 6/10 (1 November 2006)

On the whole, I enjoyed the movie, but there were certain things I did not understand and now may have to go back and rent 1 and 2 again to see what I missed. When Jigsaw is in and out of consciousness, he has visions of a blonde woman...who is this? Is this his wife? When he is saying, I love you...I love you...and he is directing this at Lynn the doctor, is Amanda jealous? What was in the envelop that Jigsaw gave Amanda? I thought maybe it was his will? In the end, did Jigsaw or Amanda kill Det. Matthews. The info on this saw 3 say that the guy who played the judge was also in the 2nd one...where? I don't understand what the guy with the chains had to do with it. I understand everyone else related to the killing of Jeff's son and his need for forgiveness/vengeance testing..but some of it I don't understand.
