I don't typically watch scary movies
the movie that scared me the most was Terminator 2, when I was 7.
It absolutely traumatized me for years
but now it's one of my favorite movies of all time
Of the horror Genre, there's Saw, texas chainsaw massacre, the old ones like Halloween 1/2, Nightmare on Elms Street, Child's Play, Pet Cemetary, the Screams..
But nothing has ever scared me to the point of pissing myself like Terminator 2. When the T1000 turned his hand into a huge blade to kill John Connor's Foster father, or when he turned his finger into a knife to kill that fat cop, or when Sarah Connor had that nightmare about the nuke..
It all scared the living piss out of my 7 year old bladder.
