But I found the ones where they spent the whole series dressed up and pretending to be in another time period so obviously gimmicky and superficial - they weren't at all documentary like as they were so lightweight - that I prefer this, where they are at least owning the fact that it is just play-acting. They're doing the commentary at the time, and discussing the changes. They can't spend more than a day in each year, because it's about how much it changed even within a decade, which I think is quite important. We think 'oh victorian education was like this', when actually, there were loads of major changes within even a decade. It shows how wrong we are when we just have one stereotype about it all. I preferred having a historian come in and actually talk about the changes - the children and teachers are more models of what she's saying, to bring it to life. they were never going to really experience it, even if they play acted it for a whole month, so it seems more truthful to me to acknowledge that properly.
