Caught some of this last night. Fascinating stuff - this is a period of history I know almost nothing about. While I was aware that my knowledge of the Revolutionary era contained huge gaps, I had no idea how little I actually knew about the "French-Indian War".
Everyone's a critic, so here's my two cents: It's a little hokey when one of the characters steps out of the scene and addresses the viewer/camera to offer some personal insight, then steps back in. I guess that's the best "special effect" PBS has to offer - besides Ken Burns'sepia photos, mournful music, and famous actors voicing historical figures.
On the plus side - love the narrator, Graham Greene.
