Agree with MsDemeanor. If as you say they're all wanting to watch the next Saw film too, and they watch it, and then the other mums find out, then find out you knew all along but said nothing, they're going to be almost as angry with you as they are at this girl's Mum. I would be, if someone knew that my child was being shown something truly sick and that there was a good chance they'd watch more of it, and although they knew for sure their own child was safe from it, they didn't do anything to let me know so that I could protect my own child. Of course maybe the mums in question won't know anything about 'saw' and so will think, like snowleopard, that their kid won't have been damaged so you might get a reply of 'So what?'. But if the mums do know anything about the series of films they'll be booking appointments with child psychotherapists before you can say 'We need to talk about Kevin'. And I think as a mum I'd be more angry with you, because you know it's wrong whereas it sounds like this other mum is just an irresponsible fw with no clue.
Miggsie, the worst thing about 'Saw' imo, isn't that there is no ethical/moral context, it's that it's full of moralising, and a child might not have enough depth to their reasoning to realise how flawed the morality is. But the moralising comes in the form of torturing people who 'deserve it'. Here's one quote below from a "Christian" review of the movie (I am not linking to it because I don't want to increase the hits on their website - the quote is necessarily out of context for which I apologise - and incidentally I am a practising Christian and find it VERY hard to relate to this review... The reviewer is clearly more of a "Guns for Jesus" kinda Christian)
" must add here, my own opinion and somewhat a justification on the amount of violence used. I may be de-sensitized to violence, but I find that though the violence in ?Saw III? is very over-the-top, I can think of no other movie that delivers just a poignant, universal, human, personal, and applicable moral as effectively"
That's why it's so scarey for kids to watch it, not just because of the extreme graphic violence & sadism, but because it's 'justified' and minimised, and some people watch it and think 'It's okay because only the bad people die'. "which ones are they?' "the drug addicts, prostitutes and criminals" "oh, you mean the poorest and most vulnerable people in our society? That's okay then..."
