i was just kidding, and was trying to show say that grudge isnt as "special" as everyone makes it out to be.
and to answer pyoro's question, i tihnk the doctor was chosen cause he was the doctor at his hospital and didnt seem to deeply caring at the cancer patient, which is the true jigsaw. and i dotn know why danny glover dies, since jigsaw "doesnt kill people" so i guess that could be a plothole. the movie deinfitely has alot of those.
