Birdsong - as in Seb F's novel of the Great War - has just aired on two consecutive Sunday nights over here on BBC1. It's been heavily promoted as the season's big drama. Personally, I didn't care for it - I found it altogether too slow and rather too beautifully staged and filmed. But I haven't read the book. I'd be very surprised if you didn't get to see it, since it appears to be tailor-made for Masterpiece Theater or similar.
