I saw the Trilogy of Terror sequel way back when. Lysette Anthony is pretty good in the stories; in the "Amelia" sequel, she plays the sister of Karen Black's character, if I remember right...but otherwise, it's exactly the same story, down to the detail; more a remake than a sequel, really.
The most disturbing story is the second one, I believe it is, where the little dead kid....
[spoiler]returns as a demon to avenge himself on his mother (Anthony).[/spoiler]
