at least Pamela showed some real affection for Richard, unlike Diana
The impression I had, almost right from the start, was that Pamela was going to be more menacing and conniving. Somehow it didn't turn out that way, maybe there were too many villainous characters at that time.
Even Phillip was double-crossing Angela, although that storyline didn't go anywhere.
Diana was a dangerous babe, a sexy robot, who took orders from the Number 1 (or whoever was in charge), but she seemed a bit out of place in her scenes in the vineyards, wearing a regular Betty Co-Ed outfit.
Diana looks better in catsuits, or maybe one of those space-y things that Ciji wore in Knots (ironically, it was Pamela who appeared
as Pamela in the sci-fi hit "V", opposing Captain Diana)
