What is there to get?? As Time Goes By is a romance! The episode where Lionel is shouted down by the Elephant lovers and (oh my) caught by Jean with his main squeeze. That night at bedtime, he gets dressed and leaves after realizing that the main squeeze won't accept separate bedrooms.
Warning: if you haven't seen the series, don't read this as I give away bits of the plot.
In ATGB there were many romances of sorts. Jean and Lionel, Alistair and Judy, Alistair and Mercury (who we never saw), Judy and the school teacher who had two children, Rocky and Madge, an imaginary romance between Mrs. Bale and Rocky, and of course the one real budding romance that just can't seem to get there between Sandy and Harry. There were probably others that I can't remember tonight.
What made this sitcom funny were the awkward moments, ie. when Lionel and Jean came home to find the teacher, who they had never met and Jean was concerned about his suitability as a mate for Judy, first thing in the morning, after an obvious pajama party with Judy. I could feel the lump in the teacher's throat but he was smooth as silk as he offered to make them coffee in their own home!
When Lionel was going to Norridge to speak on his book, he took advantage of the situation to hook up with what I took to be an old squeeze, not an active main squeeze (a process called recycling, btw) the awkward moments ensued with the unexpected arrival of Jean and Judy. I could feel the lump in Lionel's throat as he was making the introductions. Another awkward moment came later in the old squeeze's bedchamber when Lionel discovered the stack of other paramours' photos conveniently located in the bedside table, ready to for rapid deployment. As I mentioned in another posting, recycling is not for the feint of heart.
So was it a romance, or a soap opera, or a comedy of errors? I don't know, but it certainly meets Barrychuckles criteria for a gentle comedy. I liked it. When it was offered daily at 11PM on Rhode Island PBS, I watched it every night and slept like a baby.
I like your Freudian assessment of the LOTSW characters. I never liked Foggy. I was distantly related to a paramilitary type who took himself altogether too seriously, who acted like Foggy, so I am pre-disposed. I was pleased when my Cousin sent him packing. I might suggest that the one true authority figure, or superego, was Blamire.
