In contrast, Jenny Sawyer of "The Christian Science Monitor" said that, "There is much to love about the Harry Potter series, from its brilliantly realised magical world to its multilayered narrative", however, "A story is about someone who changes. And, puberty aside, Harry doesn't change much. As envisioned by Rowling, he walks the path of good so unwaveringly that his final victory over Voldemort feels, not just inevitable, but hollow". In "The New York Times", Christopher Hitchens compared the series to World War Two-era English boarding school stories, and while he wrote that "Rowling has won imperishable renown" for the series as a whole, he also stated that he disliked Rowling's use of deus ex machina, that the mid-book camping chapters are "abysmally long", and Voldemort "becomes more tiresome than an Ian Fleming villain". Catherine Bennett of "The Guardian" praised Rowling for putting small details from the previous books and making them large in "Deathly Hallows", such as Grindelwald being mentioned on a Chocolate Frog Card in the first book. While she points out "as her critics say, Rowling is no Dickens", she says that Rowling "has willed into a fictional being, in every book, legions of new characters, places, spells, rules and scores of unimagined twists and subplots".
