Dickens is a funny one. He’s revered as a great author today, but at the time he was the “Eastenders” of the day - his novels were published in serialised form, in newspapers, and were generally regarded as what we’d call pulp fiction. Critics and authors generally reviled him. The public adored him.
After his death, he fairly rapidly fell out of fashion.
We put these people on pedestals for the oddest of reasons. Dickens is revered as a result of a wartime (WW2) nostalgia for seemingly saner times, which has self-perpetuated to this day.
