SS-GB is the Beeb's latest drama, based on Len Deighton's 1978 novel, and it imagines how different the world could have been if Nazi Germany had won the Battle of Britain – and shows London taken over by the SS.
It kicked off with the first episode tonight (February 19) and from what we can tell so far, viewers at home were hooked.
The five-part mini-series drama is written by the team behind the latest James Bond movie, Spectre, and stars Kate Bosworth and Sam Riley.
Looking to viewers' reactions, the audience at home were mostly alarmed by the bleak, apocalyptic style Britain full of fascists being a bit more familiar than they'd like...
(Oh, and the whole 'WTF, wasn't James Cosmo just on Big Brother' aspect, and the standard gripes about actors 'mumbling' 'completely incoherently' causing people to have 'no bloody idea what's going on'.)
Some people were disappointed that the show didn't live up to their expectations, after being hyped so heavily by the BBC...
And some viewers, unsurprisingly, found time to compare the show to The Man in the High Castle, what with both series being based on novels imagining dystopian alternate futures where Nazism reigned.
But at least there were some viewers making sure that the important political issues of the show were being remembered.
SS-GB will continue next Sunday (February 26) at 9pm on BBC One.
