Or maybe most folk don't get upset about nor count how many black people are in something or make comments like "skip any scenes that include black characters only."
Seems you have some unresolved issues regarding race.
That comment related to last few episodes which contained a lot of filler, episode 1-6 were decent, the rest didn't really work for me, and it just so happened that a lot of the scenes involved Rose and the brother which didn't really interest me or add much imo, two more characters that were race swapped and gave forgettable performances.
I have issues with forced diversity, no issues with black leads or even movies with predominately black characters within reason, it was never an issue in the 80s/90s. Nobody went to see an Eddie Murphy, Denzel Dashington, Samuel L. Jackson or Wesley Snipes film and think there are to many black people, we just enjoyed the movies, because nobody made an issue out of race, so typically characters were never race swapped. Also helps that Blade in the comic was actually Black. lol
