As a lifelong fan of Abraham Lincoln, I had to get the book as soon as it came out. The narrative is richly detailed and informative and fascinating - there's so much, in fact, that the documentary couldn't encompass it all.
Something not much remarked on by other reviewers here (at least that I could find) is how funny many parts of this documentary are. I think Lincoln himself would have laughed out loud at the humor. The humor is aptly placed - it centers largely on the mind-bogglingly inept criminals at the heart of this story. Example: one of the criminals specialized in counterfeiting...nickles? Think Keystone Cops, and you'll have an idea.
Of course, book and documentary alike are tender and touching when it comes to Lincoln and the people who loved him. The narrative is respectful of the history, and as noted by others here, the technology used to bring the story to life is interesting (but never overwhelms its purpose).
This is one of our favorite documentaries on television, and every time it comes on, whatever the hour, we stop to watch it again...we're watching it right now, in fact, while I write this review.
For anyone who thinks history is boring, this is the documentary that could change their mind. We viewers are lucky that such care, attention, and intelligence was devoted to putting this film together.
Book and documentary alike are HIGHLY recommended! They complement each other perfectly - and the author is not only an excellent writer, he also one of the many delightful, deft and knowledgeable historians who appear in the documentary!
