I don't remember much of the last few seasons of ATGB. A few things I do recall of the later parts with lukewarmness. More on me I guess because a plot line or two did not play out as I would have liked.
One episode I do recall with a chuckle was when the ladies thought Lionel was losing his hearing and encouraged him to see a doctor about it. I also really liked Lionel's Dad Rocky and Madge plus Mrs. Bale with her weather reports on the Channel. Lol Ferris the gardener, Penny and Stephen added some humor.
A neat bit of trivia is that Dench's real life daughter and Palmer's son are in some pictures during the opening title sequence. Both appearing as a younger Jean and Lionel. A nice touch of detail, I think.
Wow, I had overlooked that there are 10 series of the show. Sorry Barry, thought it was shorter than that. Oops.
