Thought part three was pretty good, especially through the use of re-enactors and computer graphics, you get a real sense of what this battlefield and a clash of two armies might have looked like on the day. Agree that the post invasion commentary fell a little short, the absolute devastation of the north was not covered enough and the lack of significance given to the Doomsday project and total replacement of the key positions and institutions of church and state was an opportunity lost in explaining what invasion really meant.
The use of the historians failed as an experiment, which felt awkwardly shoe-horned into the program, strange really because having an element of docu-drama, we already had faces and voices of the three leaders in the form of actors and they could have adequately performed the role that the historians were given and this would have felt a bit more organic to the presentation.
Overall though, I thought the series was pretty good and I would like to see other topics given the same sort of treatment. It seems essential to me as a UK resident, that a general understanding of our most famous and significant battle and point in history is kept in the mind of the general population. There used to be a saying that every schoolboy knew of 1066 and of recent years I had started to doubt that, programs like this can only help in re-asserting adequate understanding of good history.
