I have to say saw3 was excellent.The plot was brilliant although john k. may seem to be dead the producers would be pushing the limit of that old man by keeping him alive in saw4,the guy bearly survived saw2 so this should be the end.I think they will use some flashbacks because i still don' get the ideea with that blonde girl that jk was filming,,,,It was awesome saw3 surely rules among films and it could be considered a psychological movie as well because it isn't just pure slaughter it is cleaverness combined with this rage against the human nature,i don't give jeff many chances because we remanined locked in the room where lynn an d jk died so it would be interesting to see what happens,but we must remmember about dr gordon and mathews's son who are the only survivours living because amanda died.I think gordon was a chance because we is a cold blooded doctor but maybe jigsaw brought light to his dar life,I can't wait to see saw4 AND CONGRATULATIONS TO THE ACTORS AND LIONSGATE AND TWISTED PICTURES KEEP IT UP!!!
