Black and White
I've been trying to work out if there is any pattern to the use of black & white, and colour, but i cant see any. I've only watched the first two episodes but the seemingly random changes are a bit annoying.
There is one scene in Episode 2 where the Nazi flags are highlighted with colour, against the rest of the scene which is black & white -- which makes more sense -- but apart from that the switching about serves no purpose.
I would have much preferred the whole thing to be filmed in b&w; as the b&w scenes definitely feel more like the 1930's. When it drops into colour i get the feeling of moving forward in time, like i have been dropped into the 1980's. The years after 1960 should be colour, and before 1960 b&w. That would make more sense to me.
Apart from that its great, ill go and watch the rest now, and pretend there are no colour scenes :)
