Considering the Harry Potter franchise's box office sits at about $7.7 billion (not including the Fantastic Beasts movies) and the eight movies remain beloved to this day, it's easy to say that the creatives behind the movies struck the perfect tonal balance.Īs a franchise aimed at audiences of all ages, going too dark and too edgy would really just be alienating people who liked Rowling's books. While the franchise may have started off as a whimsical and wondrous adventure, each subsequent installment becomes a little darker, with the story and its themes becoming more grown up as its characters do.
