If you can make an animal into a person, how long do you think it will be before someone can make a person decent?
Edward Prendick survives a shipwreck and is rescued by a supply ship headed for The Island of Dr Moreau. Prendick is cast overboard by the supply ship and is thus stranded on the island where he discovers a mad scientist (surgeon actually) has been at work for many years. The locals are huge fans of vivisection. Things go downhill when Brando is cast as Moreau.
I mostly enjoyed rereading this novel, and I definitely understood more of the issues than when I read it as a kid. At the time HG Wells wrote this famous tale, there was much debate in Europe regarding degeneration (https://en.wikipedia.org/wiki/Degeneration_theory), evolution, and vivisection. Wells himself thought that humans could use vivisection for evolutionary purposes (https://en.wikipedia.org/wiki/The_Limits_of_Individual_Plasticity). And what better way to discuss these issues than in a science fiction novel.
There were two main issues that stopped me enjoying this novel more. The first issue is common to all of the HG Wells novels I have recently reviewed, and that is the dated style that drains a lot of the tension out of the narrative. The reader is always left at arms-length from the story. The second issue is a narrative device that is still commonly used today: book-ending. Book-ending (a term I've probably made up) is where the actual story is wedged between an external narrative that is used to recount the story proper. This does two things that annoy me: it adds needless narrative and characters; and it destroys any suspense or mystery. The latter is the worst part. In The Island of Dr Moreau we already know that Prendick survives the island and his experiences have left him emotionally scarred and unable to live among people, because his nephew introduces the tale after finding the manuscript when Prendick dies.
Regardless, this is a creepy tale that is worth reading even if you just want to learn to recite 'Are We Not Men'.
