Query: Interesting topic but unfocused book

Am I the only one who didn't love this book? After reading about Shackleton's adventures in the book "Endurance", I longed to read more about antarctic exploration. However, "The Worst Journey in the World" fell far short of my expectations. The first half was too long and not written well enough to sustain my interest. The author kept going off on tangents that made it hard for me to focus on this book. The story picks up in the second half, but I was sorely disappointed. Check out "Endurance" for a better read.
