I received a copy of The Terminator for Christmas when I was 7 or 8. My mom used to sometimes, while Christmas shopping, buy a thing or two that was really for herself, but put it under the tree for us kids. I have no idea why. Needless to say, I watched the hell out of that movie, and it’s still one of my favorites.
Jaws traumatized me at 6. I remember being unable to watch Quint’s death for years specifically because of the blood coming out of his mouth. I could not fathom as a child how a person could be eaten from the feet up, and be bleeding out the mouth before the shark’s teeth were anywhere near it.
