Is this true? It doesn’t tally with my observations, but I try to minimize my exposure to popular culture.
Something that is often forgotten about J.K. Rowling’s books/movies is that while they started out being almost equally popular among girls and boys (the authoress chose old-fashioned initials to hide her sex from little girl-hating he-men), by the time the eighth and (sort of) final movie in the series finally came out, their appeal was almost wholly to girls, just as J.R.R. Tolkien’s fans are overwhelmingly male.
The bit about Tolkien fans would be news to the rat maiden at the too-long-idle Quenta Nârwenion.
