Look obviously this show is not going to have a shoestring budget if it gets made. It just wouldn't be an MCU movie budget. Most of it would also be set in New York anyway. The whole thing doesn't have to be shot in K'un L'un. You would also think you can do K'un L'un on sound stages.
Also the Carrie-Anne Moss thing...look, it's hard to get excited about that she's playing a character connected to Iron Fist. In the long run, that doesn't necessarily mean anything. Case in point, Madame Masque is going to be a villain on Agent Carter, who will never in fact meet or beguile Tony Stark. That means we are never going to see Masque in the modern MCU causing trouble for Stark/Iron Man. Also, they've gender-swapped Moss' character. In other words, all bets are off.
Now obviously, I am not sure about the truth of the Bleeding Cool rumors. But I am however nervous that it seems everything has been lined up for Marvel on Netflix except Iron Fist. We have no lead actor. No writer or showrunners. You would think they would at least have that by now. I wonder what the hold-up is. I am a little concerned. You think they would at least have a showrunner by now.
My other problem is that Marvel Studios needs to really start embracing the mystical and fantasy qualities of Marvel. Not every aspect can be hard gritty no super-powers etc. I mean, yeah, you want dark and gritty for these shows, but there are still supernatural and fantastical elements. Just because they are there doesn't have to mean they are stupid. We have a talking raccoon and a giant anthropomorphic tree in Guardians of the Galaxy. Why can't Iron Fist have a hidden city in Asia and a master martial artist with super falcon punch powers?
