As a long time student of history in general, and British naval vessels from the age of sail specifically, I am usually disappointed with the accuracy and thoroughness of movies, documentaries and even TV series. I remember the History Channel used to make valiant effort, and its demise into mere episodes of modern fisherman and truckers was literally preceded by a descent into amateurs and hacks, which must have been evidence of some gigantic political agenda in which budgets were slashed. There were a few bright spots over the years, like Monte Markham's series, but people like Michael Hirst sold us out with apparent enthusiasm. So...this series not only reviews the best stuff I have ever seen or read, it explores alternative theories, and is simply bursting with professionalism. And yes, I learn a lot of new stuff with every episode. It's enough to reduce my ego. Which is a good thing.
