I'm going to echo what I have heard here. I soooo don't hate it. I'm enjoying the Eff out of it, to be perfectly honest.
I find Finn Jones to be so refreshing. I hear people complain about his "vanilla performance," but I think he is acting like a young man who spent 15 years with monks in some magical land, training and taking his job as Iron Fist hella seriously. Consider that he hasn't been socialized in the same way people in the "real world" have. He's naive and innocent in many ways and is learning how much of an outsider that makes him.
Disclaimer: I do not know the comics or know ANYTHING about them, so I am not sure if this is true to character. But it is how I am reading it.
I've heard critics complain about the fight scenes, but I have found them engaging and badass. Danny moves with a very marked fluidity, IMHO. He isn't busting through walls like Luke or Jessica, or flipping around doing spinny, flashy moves like Matt/DD. He shows great control.
I really like it.
I like the siblings, Ward and Joy. There is something really tortured about Ward especially and Joy is a compelling character (even if I don't fully trust her yet). I am only on episode 5, so I still need to work through more of it.
Where people were saying, "Meh, I gave up after 2-3 episodes," I have had a great time and I look forward to seeing Iron Fist working with the other Defenders. He will bring some balance.
