"Barbara, remember The Promise". It was 35 years ago when I saw this episode. It scared the daylights out of me then and I still remember it to this day. Definitely a CLASSIC. I wish TVLand would rerun this show. That and Circle of Fear.
This was when scarey movies/shows were just that - scarey - not the gross out masacres that they are now. I loved scarey movies when I was a kid - they were truly creepy and terrifying. Now they are just gorey for the most part. I wish film makers today would give us the credit of a little imagination.
