Excellent and entertaining. Chris Rock was surprisingly good in a serious role... Not academy award calibre acting, but still good. Story was interesting.. Unlike the last few films in the SAW franchise where it was basically just "how bad can we gross people out by watching horrific torture scenes", this one was still gruesome, but led more to the story than it did the shock gore.
In all the franchise, in my opinion, the first 2 original films were the best, then comes this one.
Glad I watched it.
