Twain’s dislike of Walter Scott animates many fine passages in his work and sometimes an entire book. If nothing else, Twain was a consummate hater and could channel that into some fine work. Occasionally the hatred is laid bare which deliberate hyperbole can’t soften. A couple of passages from Life on the Mississippi:
Sir Walter Scott is probably responsible for the Capitol building; for it is not conceivable that this little sham castle would ever have been built if he had not run the people mad, a couple of generations ago, with his medieval romances. The South has not yet recovered from the debilitating influence of his books. Admiration of his fantastic heroes and their grotesque 'chivalry' doings and romantic juvenilities still survives here, in an atmosphere in which is already perceptible the wholesome and practical nineteenth-century smell of cotton-factories and locomotives; and traces of its inflated language and other windy humbuggeries survive along with it. It is pathetic enough, that a whitewashed castle, with turrets and things--materials all ungenuine within and without, pretending to be what they are not--should ever have been built in this otherwise honorable place; but it is much more pathetic to see this architectural falsehood undergoing restoration and perpetuation in our day, when it would have been so easy to let dynamite finish what a charitable fire began, and then devote this restoration-money to the building of something genuine.

But wait, it gets better:
Then comes Sir Walter Scott with his enchantments, and by his single might checks this wave of progress, and even turns it back; sets the world in love with dreams and phantoms; with decayed and swinish forms of religion; with decayed and degraded systems of government; with the sillinesses and emptinesses, sham grandeurs, sham gauds, and sham chivalries of a brainless and worthless long-vanished society. He did measureless harm; more real and lasting harm, perhaps, than any other individual that ever wrote. Most of the world has now outlived good part of these harms, though by no means all of them; but in our South they flourish pretty forcefully still. Not so forcefully as half a generation ago, perhaps, but still forcefully. There, the genuine and wholesome civilization of the nineteenth century is curiously confused and commingled with the Walter Scott Middle-Age sham civilization; and so you have practical, common-sense, progressive ideas, and progressive works; mixed up with the duel, the inflated speech, and the jejune romanticism of an absurd past that is dead, and out of charity ought to be buried. But for the Sir Walter disease, the character of the Southerner--or Southron, according to Sir Walter's starchier way of phrasing it--would be wholly modern, in place of modern and medieval mixed, and the South would be fully a generation further advanced than it is. It was Sir Walter that made every gentleman in the South a Major or a Colonel, or a General or a Judge, before the war; and it was he, also, that made these gentlemen value these bogus decorations. For it was he that created rank and caste down there, and also reverence for rank and caste, and pride and pleasure in them. Enough is laid on slavery, without fathering upon it these creations and contributions of Sir Walter.
Sir Walter had so large a hand in making Southern character, as it existed before the war, that he is in great measure responsible for the war. It seems a little harsh toward a dead man to say that we never should have had any war but for Sir Walter; and yet something of a plausible argument might, perhaps, be made in support of that wild proposition. The Southerner of the American Revolution owned slaves; so did the Southerner of the Civil War: but the former resembles the latter as an Englishman resembles a Frenchman. The change of character can be traced rather more easily to Sir Walter's influence than to that of any other thing or person.

As I said...consummate.
