On review, I maintain that it's at equal to the other Marvel Netflix shows, and at worst, only a little lesser.
The Meachums became a surprisingly positive part of the series - the series manages to veer fairly close to each of those three characters without it feeling too padded, and by the end, a couple of the major beats from Thomas/Kane origin series are satisfied.
There are LOTS of hints dropped at the further world of Iron Fist and the overall mythology, and it's one of those things which you hope they'll tackle in further seasons but it's also easily doubted,considering the focus of season 1.
I disagree that there's nothing memorable here - I thought the chemistry between Danny and Colleen was more compelling then any of the other romances we've seen in these shows to date, and the fight scenes are mostly well done, although it's true that there's nothing as kinetic as the hallway scene from Daredevil.
Finn Jones plays a breathless and determined Danny, which is fine, but we don't really get to see any of the joy or charm of the character. I suppose that's fair enough, as having a slightly upbeat Kung Fu artist might contrast badly with the psychotic nature of the villains, but if I had a major criticism it's that Jones' casting a Rand didn't feel as true to the character as Colter and Cox before him.
If I have hopes for the future it's that more from K'un L'un is brought in - although, I'm doubtful, and think the show will mostly remain in New York. I'd love to see Yu Ti and perhaps Master Khan as a villain, and obviously the big drawcard would be a complete set of Immortal Weapons - that is if there's a season 2 (which I'd bet on).
I think the show, like some of the Marvel Movies before it, fails in that it is so heavily restrained by continuity (Gao) and setting up links between the shows (The Defenders) - if you were doing an Iron Fist show in it's own continuity, I'd imagine there would be significant changes.
