Man, this book has an excellent premise. Who doesn’t like the discovery of a new land with dinosaurs and saber-tooth tigers? And then there’s a mysterious live evolution motif Burroughs starts running. However, that thread is left dangling, along with the rest of the party, what happens to the Germans, etc. The middle of this book was perfect.
It was the edges that brought the book down. The time to get to the island was too vast at the beginning. The ending was too rushed. I felt like we spent 80% of the book getting TO the dinosaurs, 15% of the book dealing with primitive man, and only 5% on wild and weird beasts of the Land that Time Forgot.
While I would recommend this book to SciFi nerds, I don’t think I can provide a broad recommendation.
