Marvel's Iron Fist Review: 3 Ups And 7 Downs
2. Finn Jones
Ignoring any issues surrounding his ethnicity, and it's still difficult to see how Finn Jones was the right man for this job. At best he's just very mediocre and uninteresting, at worst petulant, immature, and entirely unconvincing as a man who trained in a mystical land and serves as the Iron Fist.
Jones' Rand is an impulsive character, which rather belies everything we know about his training in K'un-Lun and what the Iron Fist is supposed to be. In particular in the early stages he doesn't seem to care for anyone but himself and his own needs, which again doesn't fit with him being the Iron Fist. He accuses characters of ganging up on him and complains a fair bit, as though the little kid who went missing in the plane crash never grew up.
This might've worked had Jones at least brought some of the charisma his fellow Defenders have, but in that department he's totally lacking too, rivalling the Meachums in the blandness stakes. Again, part of the problem here is with the writing of the character, but Jones does nothing that comes close to elevating it. Add in the fact that he quite clearly can't handle the action requirements, and it's hard any level he works on as a lead in the show. In fairness, he might work a lot better in The Defenders, where he just has to be part of the team and can play off superior characters/actors, but he can't carry a show on his own shoulders.
Towards the end of the season, Davos - who somehow didn't become Iron Fist, despite seeming more qualified for the job - says: "Wow, you're the worst Iron Fist ever." He probably doesn't know just how right he is.
