This. Not a "scary" movie in the conventional sense but incredibly disturbing and sickening. It's the only movie I've ever watched where I genuinely wish I hadn't afterwards. Actually made me pretty angry as well. There's no way the director and producers of that film can hide behind "artistic licence" there's no artistic reason or need to make a film like that.
I've not spoken to anyone who's seen it and not been repulsed. If I could unwatch it I would. No artistic merit at all.
