Not as good as some of the other films, but not the worst. Besides the first movie, we only see these movies because of the gore. This one is alright with that. Opening autopsy was really gross. That first 2 man fight in the beginning was painful to watch. Scalp scene was also brutal. None of these scenes really pushed the limit though, unlike Saw 3 and 5, and those were the only fun scenes in the film. Much more slow as well, though not as slow as 2. Overall cheap acting and thin plot. MILD SPOLIER(didn't like how my favorite character was killed.)
