Final Destination 3.

The twists felt like retreads of the previous films. The identity of Jigsaw's accomplice is very obvious and kind of rips off the first movie's big reveal. Another aspect of the ending reminded me a lot of Saw II's twist. I'm still confused by the major twist, as were numerous people in the audience. All I will say is that Saw IV attempts to pull off something that a recent film did, but doesn't do it as well.

The new killer is Detective Hoffman (Costas Mandaylor)

although it was basically Saw 3.5, with the whole taking place at the same time thing, and the same story of a person going through numerous tasks with other lives in their hands. The twist was the weakest so far, but I'm very intrigued to where this is going. Was Hoffman working with Jigsaw? If so why did Jigsaw leave a tape that seemed to surprise Hoffman (or maybe he wasn't and I couldn't tell). Plus what was really in that envelope to Amanda. And wasn't Obi's connection supposed to be explored? And a few characters may or may not be dead, hopefully some of this is answered in the next film

When what we first thought was the beginning of the film turned out to be the end Hoffman's reaction to the "wax tape" makes sense. The tape said something to the effect of "if you thought you would get away without being tested, you're wrong." Hoffman thought he was free and clear until he heard that tape.

I didn't really understand the lawyer's (Art) association with Jigsaw and why was he being punished. Was it Hoffman who kidnapped him and stitched his mouth shut?

Is Hoffman a copycat killer infatuated with Jigsaw? Didn't really get how he fit into the mix and how he had any association with him. I thought Amanda was his only disciple.

The story being told in flashback perspective was kind of neat. I didn't really get the final scene where Agent Strahm shot Jeff after he killed Jigsaw. I think what made the scene confusing for me was that it was edited so tightly with Rigg's scene with Matthews, Art and Hoffman.

why would Agent Perez be so stupid to mess with such an obvious trap? I could see if these were cops new to the Jigsaw stuff, but they clearly knew enough to know not to toy around with those things, especially when there was no urgent reason to do so.

First off, I had no idea the autopsy was actually the final scene. It only makes sense once you've seen the entire film, but it just seems to me like another stupid "twist" to add to the already weak script. Almost all of the traps were pretty lame. They were completely implausible. The only one I liked was the first trap Jigsaw made for Cecil. I liked seeing his beginnings in the art of torture. But what was up with this Det. Hoffman guy? Now he's the new Jigsaw. Why? Do we really need to see more of Costas Mandylor in future sequels? I don't. They don't even explain his motivation for aiding Jigsaw. It's like Friday the 13th part 5 except forget the ambulance driver's son got killed, and instead he's just some random dude that dresses and kills like Jason. And wtf was up with Angus MacFayden? It's like the duo that were writing the script got 80% done and then one said, "Shit, we forgot all about that guy left in the building at the end of Saw 3! What should we do?" So the other said, "Let's just have someone shoot him as soon as he pops up. Now we don't have to deal with resolving his story." "High five!" And this guy from Gilmore Girls as the captain? Could he have been any worse of an actor? This movie sucked so bad it hurts my brain.

I agree 100% on your comments of bringing back Angus McFadyen for 1 scene. It made no fucking sense. I think it was more or less a last minute addition.

Nothing in the final scene explained why Hoffman was an accomplice in the 1st place. At least Saw 3 explained why Amanda became involved with Jigsaw and tied up all the loose ends from the previous movies.

They writers never explained how Art got to where he was. He had some weird contraption on his neck, but never explained how it got there. Was he aiding Hoffman?
