2nd part of 6 was on earlier. Anyone else watching this? This is one of the best pieces of television I have seen in a long while - and it's on the BBC, FFS. Gripping, intense, funny, - complete silence ruled in my house tonight as it did last week while this was on. Without going into the obvious talents of Michelle Ryan (there are other threads for that!), every single performance in this was superb. Will be glued for the remaining parts, this has got me fixed in a way that only 24 has previously been able to do.
