I want to see the same thing in the show that I want to see in the comics:
I want the writers to utilize all the differing characterizations of Danny over the years and realize that, together, they help to show a three-dimensional, complex character who acts differently in difference situations just like any real person.
And y'know what else I'd like to see in the show? I'd love to see Danny's power portrayed as it is shown in The Living Weapon, with his bones showing and whatnot. That was just an awesome move on Kaare Andrews' part, I think.
Oh, as for the "white savior" stuff, I'd like to see some subtle foreshadowing that making Danny the Iron Fist was a "plot" all along by those in power of K'un Lun. Danny's role as Iron Fist should be just as much curse as gift. I think that would somewhat subvert the uglier aspects of the cultural appropriation.
-Pav, who has seen the vaguest of hints at this in the comics but would like to see it played up more overtly...
