This isn't even a real review. All you're giving is a biased summary of the plot with very little to do with the actual movie, but rather the franchise.

Well what can i say about saw 3 that hasnt already been said...well loads actually.as in the first and second instalment i highly anticipated a good story ,good characters,and enough suspense to make me think the 1st and sequel never excisted,well the first one does,and the second one certainly does,this movie was a disaster from chapter one,the acting was wooden the torture scenes were far fetched .You may say that they are meant to be far fetched but hey the boundaries have to be bettered more then gorier. the whole story of without tryin to spoil it,,husband and wife issues, was boring,i always look forward to a nice little twist at the end of the saw movies and this one was no exception,but the twist left me baffled and askin questions.One question is how can they be making a 4th which they promised,my guess is they will back track and claim the goings on in number 4 happened before number 3,which confusingly would have to happen before the events of number 2....yeah im confused to.
