I first watched this 40 years ago, the evening it was shown, I was 14, completely terrified by it & it was all we could talk about at school afterwards.
It has played on my mind for the years since, you can keep your Hostel, Saw, Annabel type horror, this is horror, show it 2 anyone & everyone, everywhere.
I have now watched it again at the age of 54, I am still completely terrified, actually more so, with age comes life experiences & a greater understanding of the world.
May this never be a reality. Please God or Whatever name your God goes by. ๐๐ป
