15. “Find reviews on Rotten Tomatoes…” “...sure to leave the franchise's followers thoroughly satisfied (and, of course, clamouring for more)...” “Saw 3D is sicko-exploitative, viscera-spewing trash, but at least it has a lean and mean pace and focus, and it isn't clotted with back-story.” “The central storyline is starting to feel really played out, but there's a palpable sense of actual fun to this alleged final film.” “For what it is, Saw 7 is serviceable.”

16. “…and I.M.D.B” “The seventh and last instalment lays down all its cards... or at least the rest of its cards. The series certainly went out with a bang to say the least. Fans and/or gore hounds will love it, and there's enough entertainment for some of those who aren't overly familiar with the series or forgot a thing or two in the previous six films. It is possibly the most appealing "Saw" film, knowing that it's ACTUALLY the finale. But where does that leave us with quality? For a ninety minute film with numerous returning characters and just as appealing brand new characters, not to mention the burden of trying to keep originality with a redundant back-story, "Saw 3D" does pretty good given the obstacles it's forced to work with. What most people will probably criticize is the lack of twists and turns that made us love the original so much... but lets be honest, has there even been any jaw dropping twists in the series since "Saw IV" or even as far back as "Saw II"? It's up for debate, but the story in the seventh instalment is pretty straight forward and that may let some people down. Given that it's a seventh film in a series with impressive continuity, "Saw 3D" is actually a really great film for what it is.”
