First, is MovieBob a brony? Awesome!
Second, I really have to agree with this. As someone who hates Tyler Perry movies, my choices are even more limited if I want to see black movies, or movies with a substantial black cast or character who isn't an idiot. Hell, they don't even come out with the as many Asian kung fu movies as they used to. I appreciate continuity as much as the next nerd, but it's nice to have the occasional character who looks like me in the realm of superheroes. I'll always draw the line on historical changes, there should never be a Benjamin Franklin movie starring Cedric the entertainer, but I thought that black heimdall was cool, and he did a good job.
