These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: One Foot in the Grave
Alas, Poor Scrappy — The Meldrews hate Ronnie and Mildred's guts, but it's hard for them (and the audience) not to feel some sympathy when Mildred is found to have committed suicide in the middle of a card game.
Harsher in Hindsight — At the end of the "One Foot in the Algarve" special, Peter Cook's character gets involved in a very fatal-sounding car accident. The special would prove to be Cook's last television role, and he died a year later (albeit from natural causes, averting an outright "Funny Aneurysm" Moment).
The Woobie — Mr. Swainey, especially in the penultimate episode, where he is shown a glimpse of a lookalike American TV reporter, after which he realises that he has done little with his life beyond helping old people, and that his "reward" for that is likely to be growing old and dying alone. Granted, he does cheer up at the end of the episode after it turns out that the reporter got blown to shreds by stepping on a landmine, but it's hard to imagine that his depression won't return at some point.
