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.
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.
Adult readers also tend to find Aunt Polly much more sympathetic; for all her faults, she is doing her best to raise her nephew and two other children on her own. Further, she's subjected to the worst fears — the loss of a child — not once, but twice, in the course of the book; her emotional torment is all too clear, especially to readers who are parents themselves.
Beatings, whether at school or at home, were quite common, and Huck even states that his back doesn't mind any more.
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." In the Wishbone version, "A Tail in Twain," he's called "Crazy Joe," and it's not made clear that he's supposed to be Native American.
The Adventures of Tom Sawyer: The Musical
Awesome Music: Mixed with Heartwarming Moments: "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.
Audience-Alienating Premise: This game tends to get a bad rep on the internet for its All Just a Dream premise alone and having little to do with the book, leaving many to write it off as another schlock licensed game.
Broken Base: Is the game another just another licensed crapfest that does no justice to a beloved book? Or a well-done Pragmatic Adaptation that, while weird, is still perfectly fine and plays well for what it is? No one can decide.
No Problem with Licensed Games: The game plays and controls well. Once you get past the weird premise (Tom has a dream), the game is a perfectly competent platformer with actually decent music.
