Iron Fist really screwed up the brand. The scenes with him doing anything more than background in Defenders are painful. They need to recast Danny, Finn Jones is a mediocre actor and terrible at martial arts (the guy can’t even tai chi convincingly, how does anybody suck at tai chi). Also they should fire all the writers that were associated with Iron Fist, they stink. Maybe just kill the character off, that’ll remove the stench from season 2 of Defenders.
Actually Tai Chi is very difficult to do.
Doing “the forms” and doing them “in structure” is very isometric. If taught & done properly some of the “the forms” take 20 minutes to do and your thigh muscles should be screaming at the end of the routine.
It’s a “stand up grappling” martial art built around joint locks. It has occasional strikes & kicks, but the “strikes” are quite often just very powerful pushes or shoves to knock the opponent off his\her feet. I took Chen style Tai Chi for a few years and it takes a lot of practice to gain the strength to “stay in structure” while doing the routines & the martial actions. Note Tai Chi has associated with it a lot of nonsensical “hocus pocus” like “Chi flow” . My Chinese instructors used to laugh at people who believed that stuff.
