The sequel to Saw, the greatest fictional exploration of the Prisoners’ Dilemma ever, is finally here, and it’s fantastic too. It isn’t as easy to pigeonhole the sick games being played this time around, but Saw II‘s got the original’s marriage of hard-edged game theory and perceptive psychology.

Disclaimer: It’s not for the faint of heart. Like most truly scary movies, there’s little gore, but your imagination fills in all the gorey details.
