Always depressing to see racism
He isn't the first black dude in Star Wars movie, ya know. However, he shares the same features as rest of the crew and that means he is some Disney wannabe actor kid like that Will Smith's talentless son. John Boyega does look a bit like young Denzel Washington but that isn't a good thing, because Denzel didn't become one of the greats because of his looks (he looks really bland and not interesting at all).
Star Wars had very memorable black character in Lando Calrissian, played by incredibly charismatic Billy Dee Williams. Also Darth Vader was voiced by James Earl Jones, who isn't just great voice actor but has a epic presence on the screen in movies he's been playing. Mace Windu was portrayed by Samuel L. Jackson, who is another iconic black actor but that was one of his weaker roles imho.
Dunno who is racist here, random people on internet or Hollywood. In the past we had already mentioned Denzel, Sammy L, James Earl Jones, Forest Whitaker, Morgan Freeman, Laurence Fishburne etc. Today who is there of young black actors (18-35 years old)? Most young actors look like typical gorillas, every single of them is white, tall with blue eyes...
