I surprised myself by agreeing with him! "Wigan Pier", "Down and Out in Paris and London" are important reportage, also "Homage to Catalonia" if you account for the very obvious bias, and even (the much weaker) "Keep the Aspidistra Flying" may be worth reading for the satire (not the characterization or plot drama, which are almost nil), but Orwell as didactic preacher ("Animal Farm", "1984", "Politics and the English Language") really is just mediocre at best. Good reporter, shallow thinker. And barely acceptable as a novelist.

Now I suppose I'd better read something by Will Self.
