Query: boring slog thru the jungle

I thought this would be a fascinating adventure strory with some cool history and natural science thrown in. Instead it was a boring, repetitive slog through the jungle that had me wishing the whole group would be slaughtered by the indians so the book would end! How many times do I need to be told mosquitoes cause malaria, T.R. was disappointed by his election loss, etc.? Where was the editing?
