THE GOOD
I loved whenever this show delved into the mythology of the Iron Fist, Kun Lun, and The Hand. We gain a lot of new information on The Hand in this, but unfortunately nothing on the literal plot hole in DD season 2. I also liked the characters. The Meachum family was very interesting, I especially liked Harold's storyline, though it got laughably corny at times.
Danny Rand himself is played impeccably by Fin Jones, who manages to capture all sides of Danny, from his child like optimism, to his status as a living weapon, to his PTSD from the plane crash that killed his parents. You can really feel all three of these things clashing against each other throughout the show. Colleen Wing had a great arc in the show.
Jeri Hogarth of Jessica Jones returns, and is great as always.
The fight scenes on the show vary but we do get to see some really great battles. My personal favorites were a battle between Colleen and her sensei in the rain, the Iron Fist against a literal drunken master, and the obligatory hallway battle( which actually ends up in an elevator)
THE BAD
Not enough Fisting
Joking.
I really wanted to see more of Kun-Lun on the show, but maybe next season. Also, the show tends to drag sometimes, especially in the first couple episodes. Episodes one and two are especially hard to complete but believe me, it gets better. Also, in the first few episodes, Danny makes some very dumb decisions that serve no purpose but to get the plot moving. These can be ignored and rationalized, but I was yelling at the tv.
Overall, I would give the show:
6 Mister Fister multi speed Vibrating Fists outs out of 10
