From the New York Times: Why Orwell Endures.
And yet for all his fame and stature, Orwell remains elusive. For one thing, he is impossible to categorize. He was a great something — but a great what? Scarcely a great novelist: the prewar novels are good but not very good, and even “Animal Farm” and “1984” aren’t great in the sense of “Madame Bovary.” To call him a great journalist, as many have done, means overlooking plenty of mundane (and inaccurate) political commentary. It’s when he turns to such unlikely matters as boys’ comics and vulgar postcards, as well as to his central subject of politics and language, that he enters the realm of deathless literature.
