World War I in Colour

I've been watching a number of "colourised" historical documentaries and although I've noted that other reviewers have raised the issue of problems improving the detail of (now very old) monochrome film whilst colourising them, it's still a shame that the end result isn't as good as some other productions.

What REALLY lets this down, however, is the constant reference to "England" when "Britain" should be used - it's a common error for Americans to think that "England = Britain" (it doesn't!) but it's unforgivable for references to be made to "England" when even the maps being displayed clearly display "United Kingdom". If this series was to be believed, Scotland and Wales didn't play any part in WW1 (Northern Ireland didn't become part of the UK until 1920).
