I saw it today. Decent! The first really funny Saw movie. The kills are surprisingly inventive without going sci-fi (like "Jigsaw" with its James Bond lasers and all). I personally think figuring out who the killer is is easy if you follow the breadcrumbs if you're able to recognize misdirection (which by movie #9 you should be used to doing), but that's OK.
I'm not really feeling this as a new beginning, though. Where they could go from here is... pretty limited. Maybe "From the Book of Saw" will be like a subtitle/banner for like an ongoing Saw anthology series with different masterminds each time.
