LOL! Quote from Macmar's review:
"And with it being British, all the black actors are slaves, and non of them go to boarding school"
How many white slaves were there in the 18th century exactly?!!! Would you sooner they were played by a bunch of blacked-up white actors?
And I'm not too familiar with boarding schools, but I don't suppose you get very many black people going to them (as a proportion). If you thought the black headmaster was a token, a black student certainly would have been. At least they didn't have an American in the cast (Richard "4 weddings/Notting Hill" Curtis-style) to make the series sell-able to an overseas audience.
The only typically British thing is the boarding school setting itself. All the characters are by definition posh, rich and spoilt, which makes it hard to identify with them, let alone care.
Watchable, but don't expect more than two series at most.
