HBO has released the first trailer for its Harry Potter TV series, set to premiere this Christmas. The series is reimagining J.K. Rowling's seven Harry Potter books, with each season dedicated to one novel. The first season will adapt Harry Potter and the Philosopher’s Stone, essentially restarting the story from scratch for a new generation. However, the trailer, which was heavily influenced by nostalgia, felt like it was copying the films rather than reinventing them. The show's visual language was almost identical to the Harry Potter films and costumes were designed to reassure viewers rather than surprise them. Critics argue that the series should offer a new perspective and explore unexplored moments from the books.
