Haven't seen this show yet, but Disney have always walked a fine, odd line when it comes to 'appropriation' in Animal Kingdom, although judging from that preview video, I don't think that's the case here.
There was a great series exploring the issue a few years ago, on (I think?), Micechat. Disney have essentially spent millions building and maintaining sanitised but accurate recreations of poverty stricken areas. One of the earlier regular complaints, prior to Everest, Nemo and the like, was that the areas weren't 'magical' enough, and even somewhat stressful. But, the world is too small and diverse of a place now to represent anything in any other way. Can you believe Busch Gardens Tampa was once subtitled, 'The Dark Continent'?
Personally, accepting the fact that many of Animal Kingdom's visitors will never have the time, money or interest in visiting these areas of the world of their own accord, I think Disney do a respectable job.
