After re-watching ITV's "Brideshead Revisited" I'm now viewing the BBC's version of "Decline & Fall", having recently read the book. They toned down the racism in the Chokey / sports day sequence, but everything so far seems well done & faithful to the book. I loved the interiors of Margot's house, they seemed to get the 20's vibe correct, probably not enough visible tobacco smoke to be true to period.
