You know, Colleen really should be the fourth member of The Defenders. She's far more interesting and impressive than Danny has been so far.
Thanks to the white jumpsuit, she's also the only one, other than Daredevil, who seems to be wearing a 'costume,' which makes her look strangely more appropriate to be at his side than Luke, Jessica or 'oh, they conveniently ripped my shirt to show off my dragon tattoo, badly drawn on 'wounds' that are going to disappear next scene anyway, and, by superhero actor standards, scrawny underdeveloped chest' Danny.
Iron Fist is my favorite of these four comic book characters, because he's got a dynamic fighting style, supernatural elements and a cool visual in the Iron Fist. The Iron Fist itself at least looks cool.
Just about everything else about Netflix Danny Rand has disappointed. His appearance, his acting, his fighting, the writing of him as a petulant and foolish child (it's definitely not all on the actor, the writing for his character has been terrible, and the fight choreographer should have realized what he was working with from the outset and minimized the big showy motions, so that he'd seem very efficient and competent, and we wouldn't see his limitations, like they do in Bourne movies or they did in old Steven Seagal movies). Ugh.
Still, the show itself had some impressive stuff, and I really liked how they tied K'un-Lun and the five elders of the Hand and their resurrection stuff and the dragon together. Nice bit of world building.
