I was trying to think of black characters in the prequels and I completely forgot about Mace Windu or Adi. And I actually like the prequels.
Another TV series to add to Kieran's list (per Tumblr):
Glue, which features Tommy Knight aka Luke Smith aka Sarah Jane Smith's adopted son who would have been revealed as gay had the series not prematurely ended aka my biggest crush when I was 14/15 aka that guy from Waterloo Road getting just a little intimate with another guy. Man, if 14 year old me were around today...
