Mostly we have been watching the Clone Wars cartoon series. It's... a lot more complex than I thought it would be, although the voice acting is a bit patchy (Palpatine, in particular, does not sound anything like Ian McDiarmaid). And we're rewatching "Trials of Life" on Amazon, and it really is extremely good.

I also enjoyed the first episode of "Secrets of the Tube," but that really does depend on you being interested in geeky details of the London Underground.
