I thought the special effects transformation of rural to industrial was brilliant, and I wish that films still used more of that sort of thing than CGI.
Didn't see all of it, though, as I was at a colleague's farewell do, with vision but no sound - I can't describe what music was on during the memorial to 7/7 instead of Abide with Me, but it was NOT appropriate. (I gather NBC cut that bit for some reason.)
I thought the choice of Danny Boy was odd (but hadn't noticed the pun), but I suppose it would have come up if people were asked "What do English, Irish, Scots and Welsh sing?" which would explain "Guide me" instead of "Gwlad, gwlad). Liked the Giant's Causeway choice, though, but that's the geologist strand of my brain.
Did you notice Ratty and Mole up on the headwaters of the Thames? A tiny brief glimpse - I had to rewind, pause and get really close to the screen to confirm them. A foretaste of the literature section - no E. Nesbit, no Just William, no Jennings, no Stevenson, no Lewis, and as someone else has said, no Tolkein.
Someone reported on the radio that a Tory MP has complained it was too left wing. Twit.
