I said that because as I pointed out, it had no other meaning! There's nothing else to say about it, as proven by even you whose trying to defend that film couldn't think of anything else.
The twists in the other films (sans IV) did have something to say and weren't just twists for the sake of twists.
It was new and different, that's nice, but that doesn't make it thematically deeper than the other installments.
I just clearly explained the thematic elements with examples, and you simply fire back with "no they're just cash ins!"
"Yeah, just cause the producers/directors/writers tried to pass off the sequels as having thematic weight, it doesn't mean there was any."
The fact that I can offer specific examples of it does, those that hate films simply choose to discard it, that doesn't mean that it's not there. SAW III clearly centers far more on the thematic elements than the first did, again, a man having to see the humanity in people he's demonized for the past year and go through a moral struggle over whether to save them or not > a woman gutting a guy to find a key.
Those pretenses are what elevate the films above the so called "torture porn" that their critics love to label them as.
The thematic elements are there, you simply ignore them and accuse the films of focusing entirely on the gore, which by ignoring the themes is exactly what you're doing.
So now this picture comment actually fits...
