I used to love this horror show in the 80's. I have every episode on my hard drive, and I have some favorite episodes I love to watch all the time today. It was low budget, and aired late Saturday nights, so a lot of the episodes weren't very good and were super cheesy.
But, the episodes that were good, were usually really good. And both George Romero and Robert Bloch were among the many writers of the 4 year series, with Romero writing, or helping write, 4 episodes and Bloch involved in 3. It was directed by Michael McDowell who went on to help write Beetlejuice and The Nightmare Before Christmas.
Anyway, I only bring it up now because it does have a Christmas themed episode and it is that time of year.
It's called Seasons of Belief, and it stars E.G. Marshall and Margaret Klenck as parents telling their children a story on Christmas Eve about a Krampus like creature called The Grither.
It's not a great episode at all. Actually, I don't think I have watched this particular episode since it originally aired. But, it was cool to see it and it is season appropriate.
So, should you want to see it, here is Seasons of Belief in all it's glory. Just remember, it was the 80's and low budget...
