Her series can be found on YouTube. In the British series, she has asides that only a British audience might pick up. The chronological history is accurate, but she brings up things that most Brits wouldn't have been taught. For ex., most would know of St George, but wouldn't know he was from the Middle East.
Origami mentioned that American public school education was a limiting factor. Ime, it's mostly a matter of what the student is expected to know versus their desire to know more. In the US, I wonder if students are still taught about the Round Table and Robin Hood. I'd understand because folklore and mythology are always easier to remember. Few people seem to enjoy "history." Imo, that's often because they're only expected to learn some dates, which they quickly forget.
Otoh, they are forced to remember some events -always linked to days they don't have to go to school.
