Literary criticism does not get better than G.K. Chesterton writing about Charles Dickens. An excerpt:
Like Napoleon, he had made his army on the march. He had walked in front of his mob of aggressive characters as Napoleon did in front of the half-baked battalions of the Revolution. And, like Napoleon, he won battle after battle before he knew his own plan of campaign; like Napoleon, he put the enemies' forces to rout before he had put his own force into order. Like Napoleon, he had a victorious army almost before he had an army. After his decisive victories Napoleon began to put his house in order; after his decisive victories Dickens also began to put his house in order. The house, when he had put it in order, was Bleak House.
