Iron Fist falls short of previous Netflix Marvel productions.
The writing was sometimes cringe-worthy and while some blame the actors, there's only so much that can be done with a poor script.
The direction was also lacking, with oddly constructed scenes and action. It felt like the actors had little feedback on their performances, which led to the repetitive silliness.
The fight choreography... well, I'm not entirely sure there was any. Unlike Daredevil (for example), where there was a genuine sense of reality in the fight scenes, in Iron Fist it felt like the scenes in Arrow. Unlimited energy, unrealistic combat, no real damage.
That said, it's not actually horrible, and makes for a good weekend binge-watch. Just imagine you're watching a 13-hour Saturday Kung-Fu movie marathon, and set your expectations appropriately.
