Watched this on Instant last night as I'm in the Halloween spirit and figured to finally finish out this series.
I've had an up and down relationship with the Saw franchise. After initially being blown away by the first movie (I was 19), I thought the second film actually had a compelling lead in Donnie Wahlberg's Eric Matthews and provocative story. The gore can be mean spirited, which I'm not always in the mood for, but the traps themselves are usually fun and II had a few creative ones. The third movie, as pointed out above, had a strong thematic message about legacies and parenting, and would have been an appropriate ending for the series. After all, as I don't buy into Jigsaw's bullshit philosophy (but at least give the filmmaker's credit for attempting a philosophy, aesthetic, and modus operandi), Amanda proving to be a failure is the only way the films should end.
Yet they kept going. IV is truly when the retcons start, everything is accelerated, and the quality starts dropping. At least the first few movies had recognizable B-listers that attempt to bring gravitas to the silliness on display. IV is like a spastic music video. It has the parallel narrative to III to add spice, and there are a few practical transitions between sets/scenes that put a smile on my face, but the leads started to feel desperate. Lyriq Bent as Lt. Daniel Rigg is a non-entity, given very little background (except that he's pissed that Hoffman is dead). What a failed attempt at giving a minority lead engaging material.
I do like Scott Patterson as Strahm, and that he holds over to the next movie, but V is a complete failure as a motion picture. Hoffman is a truly boring killer and lead, and a problem of the progressing movies is that John was never a lead and mostly maintained a mystique whereas we're privy to all of Hoffman's actions. How is Hoffman so ninja clever? At least the earlier movies had the "main character" dealing directly with the traps, but here there's a half dozen faceless characters I don't care about (and only recognize Julie Benz with a bad wig job) stuck in a trap while Strahm fumbles around the city picking up clues to a mystery the audience is already in on. VI, as has been pointed out, is an improvement as it feels topical and the trap framing device is again focused on the main character. Still, Hoffman and Jill suck. I will admit, however, that every time someone manages to escape a trap it is a bit of a thrill, and Strahm's escape at the start of V and Hoffman's at the end of VI went a long way to winning my good will towards this last film...
So, The Final Chapter fails on so many levels. The gore looks very rubbery. The traps have become completely gratuitous, now jumping to the money shots in flashbacks without any set up. The best part of the movie, the opening public trap, has nothing to do with the rest of the plot, which is unfortunate because it would've added a new shade to this whole debacle. Maybe Gordon and Hoffman could've been competing with different methodologies? Whatever. It's become apparent at this point, although II and V did an alright job at faking it, that the screenwriters have no idea what real cops are like. This is like the worst episode of CSI ever, and I felt myself going numb to the whole thing. If the first had a twist, and the second puts a twist on that twist, and third attempts thematic weight, and the sixth tries to take a poke at politics, this movie has nothing to say. Those other examples at least prove that by chance, the odds of putting so many minds together produced some semblance of quality. This felt like a complete cash-in.
All it has is the Gordon revelation, which feels completely obvious in retrospect. In a series that prides itself on looking back in on itself continuously, Gordon was never given any closure. Adam's body was shown in the second movie, we find out characters that were thought dead are actually alive (only to die again), but not Gordon. I'm thinking the filmmakers kept this in their back pocket for years, hoping to shove it into any script once the franchise ran out of steam.
