I'm just go & say this. I understand why there is a white guy playing is Iron Fist, because in the comics the Iron Fist is white. Yes I know that there was a Black woman Iron Fist, an Asian Iron Fist & who knows that other type of Iron Fist is out there.
Now I think we do need to quit casting white people in non white roles so we can have a better diversity in this modern world. I think that is a big step backwards is diverse world we live in. Do I think that we have no real choice in who is playing in a role of the character. No we don't. So the thing we can do is see if it works or not.
I personally don't have Netflex. So I can care less is this shows fails or is a success in the near future. At times I just wish people just see if the person playing the role of the Iron Fist is good enough to live up to the hype of the show.
