Please, PC ethnic diversity has no place in with messing with established characters. It was a lame, pointless, and insulting to fan's who grew up reading about Nick Fury for years. They wanted to add a Samuel L. Jackson like character to the mythology, create a new character in his likeness, or use a long standing african american character like SHIELD agent Gabrial Jones to build on! Dont **** around with Nick Fury just to add "ethnic diversity" to the story.
Besides, I dont think much of Millers writing (especially in regards to how he handled Hulk) and the Ultimate Universe in general (Heroes Reborn pt. 2), and Im glad UA actually took liberties of his story and "fixed" certain characters and made them closer to the "616" universe.
