Is the Ending Happy or Sad?
Most readers describe the ending of The Island of Doctor Moreau as disturbing. How you feel about it usually depends on what you hoped for the characters and what you expected H.G. Wells to do with the story, so it is worth asking friends how they felt before you compare notes.
Who Will Like This Ending
Readers who enjoy endings that are disturbing will find a lot to talk about here. If you prefer every thread tied up neatly, it helps to know in advance how H.G. Wells closes the story, which is exactly why many readers look it up. Either way, the final chapters reward a second look once you know where everything is heading, because small details from the middle of the book start to matter. If you are reading with a group, agree beforehand whether everyone has finished, so nobody has the last chapters spoiled.
Book Versus Adaptation
The 1996 film with Marlon Brando changes many details of the ending.
