Let us, in the interests of World Peace, agree that we may respectfully differ on the point.Ahh but Tolkien created a world unlike any other. And it spanned thousands of years. Harry Potter takes place basically in a whimsical England.
Of course there’s more humour in HP, it’s written in a whimsical style reminiscent of Roald Dahl. And as much as I love Rowling, her constant need to rewrite the characters on Twitter is a bit disappointing.
Both achieved their respective goals, but Tolkien seems to have a bit of a firmer grasp of his world than Rowling does. (Though I’m still a huge Potterhead.)
