The full video hasn't taken off on YouTube as much as some might expect, I think the view count is somewhere around the 250k view mark when usually you'd expect it to go into the millions. The comments on the video aren't very nice either. Quite a bit of racial tension in there.
Personally I hadn't even noticed the colour, same way no-one tends to notice the Simpsons are yellow.
Being a rather tragic individual, I tried to engage in a debate about the idents and film with customers at work. The general view was "Oh, yeah, I saw that. What was it for?" Not one mention about skin colour (like yourself I didn't identify the characters to be anything in particular other than a father and daughter)and not one comment about it being festive. When I explained to one that it was BBC1's Christmas ad, they said "Was it? I thought they were flogging something!"
If we only get one life, why does it take several attempts to get it right?
