Scholars have been wondering about the adult appeal of the Harry Potter series for a long time. Nicholas Tucker, a scholar of educational psychology, published a paper about the topic in 1999, after only three of the seven books had been published. He believed that it was a combination of the fantasy world and lack of contemporary social issues that made the wizarding world the perfect escape for adults.
However, as the series progressed, the story got much darker. The series experienced a lot of major character death, slavery metaphors, social discrimination, and genocide. By the time the series ends, Tucker’s theory about the series’ lack of social issues becomes completely invalid.
