The one I vividly remember was Jaws; I was 4 or 5 years old… I know my folks are weird. It scared the bejezzus at out me; even going to the bathroom was terrifying :-)
If that fake looking shark did such an impression on me I can’t even fathom a kid today watching a well produced horror movie in 3D. yikes
