Just found your site after looking for the Mud Monster- that movie gave me nightmares, literally!
When I was 8 my parents thought it would be a good idea to take me and my brother to see “Alien” in the theater. (They must have thought it was just a space movie or something) Of course, we got there late and each had to sit alone in the packed theater since there were only single seats left!
Somehow I made it through the terrifying movie all by myself, but was so scared that my brother and I slept in the same bed that night! LOL
