The first part of Saw was a very interesting thriller, indeed. A nicely claustrophic story, pleasantly disgusting visual style, good twists in the plot and a very satistfactory ending, with all the good efforts of the nice people in vain. I like that. What to do after that: Lock up more people, involve more outsiders and kill more of both. While the plot of the first film is still very vivid in my memory, I have to admit that while I remember the outline of part 2, it is hard to remember the outcome of it all. Too many people, most of them dead by the end of the film, and no real improvement on any aspect of part 1. Regular sequel fate…
