I'm a supporter of the SAW franchise actually as it's one of the few horror series that seems to actually be uncompromising with censors when it comes to brutality. I'm one of those sick guys who likes his horror to actually be brutal and horrifying, not some psychological exercise in implied violence.
That said, I *DO* tend to agree that the writing has gotten progressively worse, involving variables and set ups that nobody could POSSIBLY predict (yet we are supposed to take for granted the bad guy does since all of them, master and apprentices, are obviously super geniuses that are just THAT in touch with human nature... uh huh).
The series has potential, but honestly they really needed to spend more time on the actual writing than the "let's come up with some fairly sadistic death puzzle that someone will be trapped in, and ultimatly fail".
But then again consider that I feel "A Nightmare On Elm Street" was the greatest horror franchise of all time. It featured a rather unique villain (for the time), a warped sense of humor, very decent special FX for the day, and a fairly decent plotline which admittedly DID get too convoluted towards the end due to what seemed to be people doing movies in the same series that had entirely differant ideas from one another.
That's a series where a girl gets strapped into a demonic high chair and force fed her own guts incidently...
The big problem I have with Saw is that I'm a romantic at heart, despite liking all of these horror movies, I am a firm believer that the good guys should win in the end, even if the victory isn't a "booyah let there be a massive celebration, all is right with the world" one. It's pretty rare when something has a real "downer" of an ending or the good guys lose that I wind up being a big fan of it (it does happen however).
Simply put I do not consider Jigsaw and company to actually be good guys, whatever their so-called justifications are. In every single movie we pretty much see the bad guys win/clean house and honestly it's surprising I keep watching them. I guess on some level I'm one of those rare people who wants to see when (and if) the good guys will ever win, along with all of the so called "torture porn".
To put things into perspective, while Freddy won rounds in *MOST* movies he winds up losing in the end. No matter how cool he might be, he's still the bad guy, and when it comes to entertainment I prefer the good guys to win no matter how overwhelming the odds.
Just my thoughts.
