Query: The River of Doubt...SNOOZEFEST!!

I cannot understand for the life of me how this book received so many good reviews. The author went off of the storyline so many times, the book could've been cut in half. I wanted to read about Roosevelts expedition, not page after boring page of boring botanical nonsense. Yes Candice Millard, you are an expert at copying paragraph after paragraph of botanical literature, BUT THAT'S NOT WHAT I WANTED TO READ ABOUT! MY WIFE WANTS HER MONEY BACK & I WANT THE 3 MO. OF MY LIFE BACK THAT IT TOOK ME TO READ THIS GARBAGE!!!!
