Technically, these two movies are from the 70's, but I saw them in the very early 80's due to my parents wanting to traumatize me when they first got a vcr. Thank you mom and dad for fucking up my head back with:
The Excorcist: I still to this day can not sit through this movie
The Evil Dead: I love the second one, I love Army of Darkness, but as soonas I see that tree start to move in this, I have to walk away or change the channel.
Now for some 80's fun:
The Amyitiville Horror: My parents decieded to have me see this a week before we moved into a new house, which had a room in the basement that was red. Again, thank you mom and dad.
One Dark Night: Only saw this once, I was 11. My sister was supposed to take me to see "The Last Unicorn" which she did, she failed to tell my mom that the two movies after that was Creepshow and One Dark Night. I didnt sleep for a week. My sister got into a lot of trouble, so it was kind of worth seeing her get grounded for the week I could not sleep.
