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.
Designated Hero: Walter is usually called the hero, despite being absent for a huge chunk of the novel. This may have been intentional, intended by Collins as a comment on Victorian sexism.
In Name Only: The late-1990s BBC television version. A letter to the Radio Times wondered why the writer had bothered to keep the same title, so great were the differences in the plot.
