Lived up to every expectation
I LOVED this movie!
Just as its predecessors, this movie kept you guessing until the end. As before you don't really know what is actually happening until the last five minutes., but the hour and forty minutes leading up to that point are so full of twists and turns (metaphorically and physically) that you must give the writers kudos (well some of them. I still worry about whoever comes up with these torture devices). There is again an array of unique contraptions to "test" the victims.
In short, this movie was brillinatly done and, as expected, heavy on the gore and bloody violence. If you enjoyed any of the previous Saw movies go and see this one. However, if you are one of those people who hates violence or cant stand gore, avoid it like the plague. This is for viewers with tolerance for blood.
