Well for a start it is very insulting toward the rastafari religion even. Rastafari is as legitimate a religion as any other and it is being boiled down into a ceebeebies show full of stereotypes of the Jamaican culture.
The fact that AnnaFalactic sees this as a good way of relating her childs culture to her from a young age is also very worrying IMO. Sorry Anna, I know it must be tough with the dad not around to provide cultural reference points but this show is full of misrepresentations and infantilizing a culture, boiling it down to something simple, comprised of simplistic stereotypes.
Maybe I need to watch more of it but what I have seen was not impressive. Although, as I said, it is still a step forward.
