Probably the least well-remembered of Wells’s three groundbreaking science fiction works of the late 1890s, The Island of Doctor Moreau has suffered even more then The Time Machine from a series of poor quality adaptations, and an odd sort of uncertainty of what the point of the story is. Whether you view the book as pleasingly ambiguous or confused in its ideas, it’s still a pleasing combination of proto-sci-fi and gothic horror, reminiscent of Tom Baker era Dr Who.
