George RR Martin doesn't understand logistics; JK Rowling doesn't understand politics; Stephen King doesn't care about Plot. What are other authors who are successful despite weaknesses in their writing?

Having weak areas of writing doesn't exclude an author from writing good books. Three (in)famous writers are George RR Martin, Stephen King, and JK Rowling. Their books show that they have either a lack of understanding or interest in certain areas, yes their stories have become famous.
George RR Martin doesn't understand how distance or money work. The value of gold fluctuates wildly from book to book and the distance between things is improbable given the travel time and level of technology.
JK Rowling doesn't understand politics, because the government of the wizarding world is so hopelessly corrupt that it couldn't function, at least not to the level that it does.
Stephen King doesn't care about plot. Some of his best books, including IT and the Dark Tower series, have weak or macgufinny plots.
What are some other examples, of authors who are famous and successful despite weak aspects?
