I watched it last year with my son who, though he has a first from Cambridge, an MA and is now doing a PhD at Princeton in Architecture, has never been exposed to much formal history teaching and has been playing catchup all the way through undergrad and postgrad studies in order to put the histoprical aspects of architecture into perspective. He found the Schama DVDs very useful as snapsots of a particular period and it sparked off a lot of post show discussion. I'm no history expert, but I've dipped into it over the years and picked up some basics, plus I've done a lot of local and family history.
