In this movie, it is proved that everything we have in excess might annoy us. Although i think that the Saw creators are total geniouses, and quite inventive to come up with all those traps. The 4th Saw movie cleary has too much gore, too many impressive scenes (such as the autopsy, or the frozen woman), overall, too much of everything. And too much of everything is too much. Thumbs up for the positive add of new pieces to the puzzle, that make the plot even more interesting and confusing, bringing up the need of the last two films to complete it.
