My review of last week's episode: The Friends of English Magic
One of the best things about magic in the world of Jonathan Strange and Mr. Norrell is that it doesn't fix things as if...well, as if by magic. It is a tool like any other, and usually less helpful than most. The mechanics are kept vague for most of the story (as I recall from the book: when there are any specifics, they're wrapped in a semi-scholarly debate about something which sounds a little like HTML code.) Magic doesn't exist in a vacuum. It neither creates nor destroys matter, but merely rearranges it, in the process staying true to Newton's third law: creating an equal and opposite reaction.
