I wouldn't allow my children to watch T.V./shows (I don't own a TV and will never own a TV). Although I like Neil deGrasse Tyson, I don't believe television is ideal for Black kids (1 day - 13 years) simply for the fact that based on research done on young Black kids, they -- from watching television programs -- will start to develop personality issues: low self-esteem and self-hate being the major issues.
Hopefully the parents control what she watches, but even Black children viewing Sesame street were developing personality issues. So, who knows what type of white supremacy may leak in even with seemingly benign shows.
As for COSMOS, a lot of glitz and glamour than I am used to, but otherwise, I think it is a good program for Black teens/adults.
