Nathan and Ryan continue their descent into the Saw franchise with Saw IV (2007), the entry that proves Jigsaw’s traps don’t stop just because he’s dead. As Detective Rigg is forced through a series of brutal tests, the movie expands the lore with flashbacks to John Kramer’s past while upping the gore to new extremes. The hosts break down the increasingly convoluted timeline, the creative (and nasty) traps, and debate whether this sequel keeps the tension alive or drowns in its own mythology.
