These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Alas, Poor Scrappy: Averted, because Sir Walter Scott was begged by a personal friend (against his own original intention) to bring the beef-witted Athelstane back from the dead.
Die for Our Ship: Rowena. William Makepeace Thackeray's highly inaccurate description says it all:
"And must the Disinherited Knight ... sit down contented for life by the side of such a frigid piece of propriety as that icy, faultless, prim, niminy-piminy Rowena?"
Fair for Its Day: Isaac of York, though a stereotypical Greedy Jew, is nevertheless depicted as grateful toward Ivanhoe and his adherents, and devoted to his daughter — while Rebecca is downright saintly.
Sir Walter Scott, in his 1830 Introduction recounted: "The character of the fair Jewess found so much favour in the eyes of some fair readers, that the writer was censured, because, when arranging the fates of the characters of the drama, he had not assigned the hand of Wilfred to Rebecca, rather than the less interesting Rowena."
It Was His Sled: Today's readers aren't going to be fooled for a second when the mysterious Forest Ranger gives his name as "Locksley". However, Scott's readers would have been kept in the dark, considering Scott was the first author to link Robin Hood's name with the word "Locksley".
Older Than They Think: Scott is sometimes credited with having transferred Robin Hood to the time of Richard The Lion Heart — but in reality he was adopting a tradition that dated back to Scottish historian John Major in early Tudor times and was firmly held by Joseph Ritson, the author of the most influential study of the Robin Hood legend in Scott's own time.
They Just Didn't Care: Though Scott contrasts his attitude with that of his friend Mat Lewis (who said, "could he have derived ... advantage from making his heroine blue, blue she should have been"), he does lay claim to enough artistic licence to include whatever details seem colourful and probable, especially as most of his readers wouldn’t care anyway.
The Woobie: Various characters at various points in the novel — but Isaac fulfils this rôle fairly consistently.
