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.
Fair for Its Day: Although some of the language and attitudes are dated, the series is no worse (and perhaps somewhat better than) similar stories from the era. Johns himself appears to have been relatively progressive for the time, being an advocate for women pilots when this was still a controversial issue (See Distaff Counterpart).
