Hint: not one real fight has ever actually looked like a choreographed kung fu movie scene, no matter how well trained the combatants
Yeah, but people who watch martial-arts movies and shows don't want to see real fights, they want to see choreographed kung fu scenes with well-trained combatants. Iron Fist was originally an homage to the martial-arts film craze of the 1970s, so that's what fans of the character want to see. You want to see realistic, unpolished fights, that's what Jessica Jones provides. Daredevil was acclaimed for its fight choreography, and Iron Fist should've been even better at it. But it wasn't, except in the episode Kevin Tancharoen directed. That was the only episode that lived up to expectations in its action choreography -- although the most memorable part wasn't Finn Jones, it was the drunken-fist fighter he went up against (and Colleen's fight going on at the same time).
