She's so nice and sweet and beautiful, and to see that done to her, even fictionally, makes you ill. In Italy, she's known as being a little dim, but she's one of my favorite actresses.
When the guy was crushing the guy's skull with the fire extinguisher over and over again until it split and brains started falling out, I thought I was gonna be sick. It's not so gory and disgusting as much as it's INTENSE.
I can watch zombie and slasher movies all day, but scenes like that one and the end of Saw where he saws his own foot off are really disturbing, although I have a morbid fascination with it. The gore does nothing...it's the context, feelings being conveyed by the actors, and psychology behind it that I find disturbing. Saw is a perfect example of it. It didn't even show him sawing it off, but you could hear him screaming coupled with the other guy begging him not to do it is really, really intense. Reality is so much more fucked up than fiction.
