The first Saw was okay.
The problem was, these movies try to talk about morality, and they themselves have inconsitent morality.
For example, they talk about how the guy in Saw actually never murders anybody, like that's true. But he's clearly murdering people in every film. Not to mention the kidnapping and the torture.
Films like Saw, Phone Booth, and even the whole morality buillshit in the Dark night are increadibly flawed philosophically and are themselves an immoral message because they try to blur the truth of moral and immoral acts.
I'll get off my soapbox now.
