Saw IV (2007)

Plot Summary: Jigsaw and his apprentice Amanda are dead. Now, upon the news of Detective Kerry's murder, two seasoned FBI profilers, Agent Strahm and Agent Perez, arrive in the terrified community to assist the veteran Detective Hoffman in sifting through Jigsaw's latest grisly remains and piecing together the puzzle. However, when SWAT Commander Rigg is abducted and thrust into a game, the last officer untouched by Jigsaw has but ninety minutes to overcome a series of demented traps and save an old friend or face the deadly consequences.

Jigsaw is dead, but his game is far from over.How you might ask? Well, if I were to explain that, it would ruin the film, but it's hard to review this film without leaking something.
The original SAW redefined the horror genre, so much so that there are now countless imitators. It packed the goods in gore and a shocking twist at the end. The sequel, which really was not needed, tried to capitalize on the same system. It failed. Yet still made boatloads of money. Hence the 3rd, and this film and of course the next one. SAW IV becomes a parody of itself, unintentionally mind you. It tries to re-capture the essence of the original from plot points to the twist, which is a staple in the series now. Why SAW IV doesn't work as well as it wants to, is because it's far too confusing and doesn't satisfy it's audience, instead it leaves more holes, that will be filled in by it's sequel, much like how this one filled in some from the 3rd.SAW IV answers the questions, such as who the blonde woman was in Jigsaw's dreams and why he covered the tape in wax. Yet leaves out other things, specifically what the letter said to Amanda. It could have easily been explained, but they wanted to leave as much story as possible to continue this franchise, which should have been over at 1 and could have been wrapped up completely with 3.SAW IV is gory, probably the worst out of all of them, but not quite as nerve flinching as the others. the first is still the best .5/10
