I did an RH rewatch last summer and it was amazing to see how well the early stories hold up.
Ilene Kristen as Delia is nothing short of awe-inspiring. The whole Jill/Frank/Delia storyline is fascinating to watch because it has very little to do with Delia's love for Frank, she'd have married a bar stool if it would make her a Ryan. Seneca was a great character in that he was written, from day one, as an overbearing ego-driven man without being written as a villain. The writing showed his POV every time. Jill was and still is a unique character - a woman whose life wasn't defined by love, who wasn't turning herself inside out to get married. Frank didn't become a 3-dimensional character for me until Andrew Robinson took over the role, then he became a believable family golden-boy with real flaws. I never wanted Jill with Seneca but I loved watching their story play out. (I didn't want her to follow Frank around forever either.)
Delia/Patrick/Faith was one of the very best stories for me. So much depth to the characters, so many great scenes. The only downside was Tom Desmond. I liked the actor and the character started out OK but the stories written for him were such dreck. Theresa, Terry the tumor, etc.
Roger Coleridge is one of my all time favorite soap characters. Ron Hale was brilliant. Loved Bob Ryan and it's such a shame the show never really wrote for him. I hated Kim. Even as a middle school kid watching the first run I couldn't believe the show was trying to sell a lousy actress as the show's answer to Laura Webber and, worse insult, a talented actress. Pairing her with Seneca was Squick City but it made a twisted sort of sense based on the characters.
