I just wanted to update this thread to say that I watched SAW IV: UNRATED EDITION on DVD this week, along with the other SAW films. While I still think it's easily the least of the series, I wouldn't rate it a total "BOMB" anymore (I'd give it *1/2 now). I think it helps to watch it back to back after the first three, instead of coming in "cold" a year later. But even being somewhat familiar with the characters and scenarios set up in the storyline so far, many people are still bound to get lost and mixed up.
