The slow pace of this show, the methodical way the main characters investigate and solve their assigned dilemmas, is what makes it so believable and realistic for a fantasy drama. There is history, curiosity, mystery, suspense, chemistry, and even humor in this unusual series. Joanna Lumley and David McCallum play off of each other very well- Sapphire with endless beauty, patience and humanity, and Steel living up to his cold, but not uncaring, nature. I don't want to criticize it for dated sets and special effects because these are irrelevant to the character development and stories. Highly recommended. ( I wish some reviewers would not give away so much, especially the ending. A major spoiler for those who have not seen the show. Why not keep that discussion for the message board.)
