Love the CH intro... Beautiful green expanse filmed from helicopter, chilled but melancholy music, cut straight to city, music ends, view is from a building right out over the skyscrapers of NYC...
CH is pretty brutal, forced removal of a foetus, rape, castration etc... You have to remember that a lot of the stuff we find funny now is simply down to the fact that these are fairly low budget '80s films, they simply don't have access to modern special effects.
What also annoys me about these new films is they often don't say very much; to me Saw was by-the-numbers horror with the interesting twist of the killer's games. I didn't find the character's engaging, I was irritated by the usual plot devices (2 cops with no backup go to check out killer's house

). Usual grimy environment etc... I watched the first half of Wolf Creek a while a go and liked that a bit more, it did build the characters up and there wasn't really any sense of the guy they met being anything other than the kind of generous country type. Still, standard horror when you get down to it.
There's also very little
art to what I've seen of this new breed of films; they roll out the stock line of 'grim basement' set or 'horrible looking bathroom' set; look at Suspiria's
art noveau interiors, lit by this sort of warm, feminine light that gradually seems more like the lurid red hues of blood; intimating violence and passion. Also the way this contrasts with the scenes where Suzy meets the professor; particularly in the use of camera angles. I think violence is being done a lot better in the far east with films like Oldboy, Secretary etc.
Meh, could go on for ages... Basically don't think they're doing anything new; just nasties with slick editing and high budgets.
