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: The Chinese Conjurer and Tiger Lily are pretty broad stereotypes by modern standards, but they were fairly progressive for the time by being friends to Rupert instead of Yellow Peril villains. They have also always been drawn in realistic style, without the gross racial caricatures seen in some other contemporary works.
Narm Charm: Most long-time fans will admit it's rather silly, but a charming sort of silly.
