"Saw IV" unfortunately starts a noticeable downward trend in the series, as the crew shifted and new writers took over. While it still retains many of the series trademarks, including gooey, gory traps and unpredictable twists, "Saw IV" crumbles under its own weight. It's a little too over-produced and a hair to convoluted for its own good. Hardcore series fans will likely find some enjoyment in it, but casual audiences need not apply. 2 out of 5.

More trivia for Saw IV
Question: A tape recorded by John directed toward agent Perez states that her partner would soon take the life of an innocent man. How did John know that agent Strahm would kill Jeff? For all he knows, Strahm could have followed Rigg through the factory rather than Jeff. The "if you're good at anticipating the human mind, it leaves nothing to chance" excuse doesn't work here. The only reason Strahm followed Jeff was because he heard Jeff hit a ceiling light with a crowbar.

Answer: Realistically there is no way he could have known. The writers were just working backwards from the plot point on this one.
