Despite what other people may say, I'm very glad that the Saw crew has decided to continue the Saw franchise. There were too many loose ends at the end of Saw III that needed tying up, and I believe that Saw IV accomplished this to the degree that it was supposed to. Sure; as a stand-alone movie, it's quite confusing. I would strongly recommend viewing the previous three before this one; otherwise, as aforementioned, you'll be lost throughout the movie. As expected, IV had all the down-right blood, gore and grisly traps that I've come to know and love from the series in addition to explaining a bit more about Jigsaw's past and the inner workings of his little 'set-up'. I understood that ALL of my questions wouldn't be answered; that's what Saws V and VI are for. But I was satisfied that some of the most important 'puzzles' had gotten a few more pieces by the completion of IV. All in all, I view the Saw franchise as a 'thinking man's horror' kind of series. If you can tie the four movies together in your mind, it makes a lot more sense and you can understand what's happening better. So, I'll give it a 10/10 for avid Saw fans like myself, and even a modest 7/10 for people that aren't too into it. Saw IV is definitely worth watching through, regardless of your stand.
