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.
Moe: Whenever Barbara was shown covered in soot after cleaning their stove, half the male population of England would have fought each other for her.
Unintentionally Unsympathetic: Tom, for his selfish attitude. He can be extremely callous to Barbara and sometimes the Leadbetters too—when Margo and Jerry have a major row, all he can think about is how it affects his prospects for getting "his" spinning wheel. Even Richard Briers said he didn't like Tom very much.
Several instances of casual racism: Tom pulling "slant eyes" for a "Confucius Say" joke, Margo being horrified into panic at the thought of Arab neighborsnote to be fair this one is meant to be seen as a character flaw, as part of Margo's general snobbishness, but it's revealing of the attitudes still prevalent at the time and it's doubtful the joke would be used in this politically-correct age, and if you pay attention you can see that Margo has an apron with a racist caricature of a black person printed on it.
