Spiral is one of the Saw movies. I thought it had a really good storyline. I like the performance by Chris Rock, Samuel Jackson and Max Minghella. I thought the movie was overall good. I know many people think some of the Saw series movies are repetitious. But in this one here, there is a good storyline and I like what it had to say. It had some action in it and some eerie points. I would say go see it. 93 minutes long. I give it three stars.
