I've read a few of H.G. Wells'
books, and I've enjoyed the ones I've read. The Island of Dr. Moreau, however, seemed a bit superficial. I didn't really get a good sense of what motivated Dr. Moreau, I never felt a sustained sense of the horror/abhorrence/fear that must have been experienced by Prendick, and I felt the book lacked anything more than a superficial exploration of the Beast Men as individuals or as a society. In addition, I felt like Wells was heavy handed in illustrating man's vanity via his propensity to play God, and heavy handed in illustrating that in reality, man isn't much better than a beast himself.
That said, The Island of Dr. Moreau was a quick, undemanding bus read, and it entertained me enough on my commute.
