- Angst? What Angst?: Huck is very cavalier about his father's unavailability and drunkenness, his mother's apparent death, and the fact that he's living on the streets—in fact, when people attempt to give him the maternal love they believe he needs, he only gets embarrassed.
- Creator Backlash: Twain wasn't very fond of the story in later years. He preferred Huckleberry Finn.
- Sequelitis: Not for Huckleberry Finn, but the further sequels "Tom Sawyer Abroad" and "Tom Sawyer, Detective." Yes, those really exist. And they were written by Mark Twain himself, too. He lost much of his wealth in bad investments and he needed to support his family.
- Unintentionally Sympathetic: Mr. Dobbins for some adult readers. When young he had very much wanted to become a doctor but was unable to continue his studies for financial reasons. Hence he ended up a country school teacher (which was not considered a prestigious job for men in the nineteenth century). He still enjoys reading his anatomy text, but then one of his students has the nerve to go through his desk and damage his book.
- However, it is also highly implied that during school hours he reads the part of the book with pictures of naked women. In front of little children.
- Values Dissonance: Beatings, whether at school or at home, were quite common, and Huck even states that his back doesn't mind anymore.
- Injun Joe has caused controversy too among modern readers. At least one animated adaptation even went as far as to rename its depiction of the character as "Tattoo Joe".
The Adventures of Tom Sawyer: The Musical
- Crowning Music Of Heartwarming: "This Time Tomorrow" - a little song by Aunt Polly as she watches her nephew, musing over the growing process of children and assuring Tom that she will always love him.
The Licensed Games
- The Problem with Licensed Games: The SETA game is just another Super Mario Bros. clone and has to do with little to none of the novel, except the characters.
