I have brought this up before and I know SST knows...... For me, the early 70s TV flick "The Screaming Woman" about a lady buried alive and moaning under ground. When they dug her up and pulled her out at the end??? I FREEEEAKED!!! I was only 5. After that, I'd be playing with my Tonka trucks in the yard and my Brother would hide behind the garage and slowly moan......heeeeeeelp meee. I'd run back inside. LOL
Darren McGaven in "Night Stalker". The episode "Chopper", about the headless motorcycle guy, killing people with a sword, scared the hell outta me!
In recent years, I sat and watched both on Youtube. BOTH were CHEEEEEEESY!
Honorable mention is the aliens in the 70s TV show.. "UFO" (The same people who made Space 1999.)
