- Alternate Character Interpretation: Why does Dr. Moreau torture his creations when they get out of line? Is it because he wants to make them more human... or is it because he fears them and what they might do to him? Or maybe a little of both?
- Common Knowledge: Because the adaptations and parodies have become more featured than the original work read, it is a pretty regular event to see the book's plot described as Moreau genetically altering humans and animals. While in reality in the original book all Moreau really does is give animals proto-plastic surgery and telling them now to act like humans.
- Nightmare Fuel: The novel mentions that the creatures can have offspring, but these are immediately eaten by the parents.
- Values Dissonance: As time goes on and sensibilities change the actions of the three main characters comes off as obnoxiously Imperialist. They never consider treating the Beast Men as anything other than subhuman creatures to be ordered around and abused. Even Prendick who is new to the island and had no involvement in their creation, even when Dr. Moreau is killed and he suddenly becomes outnumbered, does not consider establishing a rapport with the semi-intelligent creatures and instead tries to set Moreau up as a god to keep them in line.
YMMV / The Island of Doctor Moreau
