I liked Space 1999’s New Adam New Eve when they come in contact with the Messianic figure.

Here's some Space:1999 trivia...there was a third season ready to produce; scripts were ready for the first five episodes. It was canceled when ITV decided it want to make a blockbuster movie that would cost more than a whole season of 1999.
It was a huge bomb. Remember "Raise The Titanic?"
