WOW! Thank you for this. Really.
I watched this entire season with painful motivation. Every three episodes, I was like "Fuuuuuuck...what the fuuuuuuck..." The most joy I got out of Iron Fist was when Davros looks at Danny and says "you're the worst Iron Fist, ever!" He really spoke aloud what I'd been saying in my mind. It felt like a really shitty version of the Count of Monte Cristo.
But after reading this, I see what my problem was: I'd been watching it with a typical superhero frame in my mind. Where he knows who he is, what his role is in life, and kicking ass one iron fist to the gut at a time. But that's not who Luke Cage is; that's not who Jessica Jones was either; and Matt Murdock has some pretty grey morals by playing lawyer by day, blind-vigilante by night. So--why should I've assumed that Danny Rand was going to be any better than these three fuck-ups forced into being the budding defenders they will become?
He's a damaged young adult. He almost DIED in a plane crash, his parents are dead, and he comes home thinking that the world he knew as a child would accept him even as an adult [which it does not]. Then he has to deal with this quasi-familiar world around him that is always looking to screw him over or deceived or manipulate him for little more than it can. Danny's too trusting, and we see the results of his too trusting nature mixed with PTSD.
So TL;DR - thank you @Admiral again for giving me another lens to see this show through. I may actually watch it again and see if it changes my initial thoughts and feelings about this show.
