HP is obviously a good, if problematic, work of imaginative fiction, it couldn’t have got as big as it is otherwise. But the themes in the books, on the other hand, lack imagination, are simplistic and are clearly meant for a child’s brain to easily grasp (which is why liberals love it so much). The division between what it is for something to be child-like and adult-like is itself a complex topic that children might struggle with and is, ironically, something that His Dark Materials, the far superior series, explores in the most beautiful way.
