V For Vendetta was a weird movie for me because while I was watching it, I wasn't taking it seriously at all, (i.e.; ending every of V's sentences with 'Mr. Anderson') yet I was still completely on the edge of my seat because of the great story.
It works on some people, and it doesn't on others. Personally, movies like Ju-On and Ringu make me a person who can be described with your screenname. Ju-On more so than Ringu because Ju-On made me feel very unsafe. The evil in Ju-On had no 'cure', no sacred ground to go to and no holy water to throw. If you came into contact with the grudge, you were dead.
