I definitely understand, but the main difference is that those characters in the movie were actually whitewashed, wherein here, Danny's not.
I think Iron Fist can open up a lot of avenues for Asian actors. When you look at the amount of potential characters in the Iron Fist mythos who aren't white, I mean, Davos, the Thunderer, Sparrow, Prince of Orphans (possibly), Tiger's Beautiful Daughter, Dog Brother #1, Bride of 9 Spiders, Fat Cobra, Misty Knight, Colleen Wing, the other 65 (66?) Iron Fists who are bound to appear in flashbacks, and possibly even Shang-Chi. And most of them are on par or better than Danny regarding martial arts, so it's confusing for me when people so harshly imply he's just another mighty whitey or white saviour.
