Being so perverse as to enjoy antiheroes, I quite liked Iron Fist season one. The Rand/Meachum family dynamics were the most entertaining I've seen since the heydays of Dynasty, Dallas and Falcon Crest.
Like most sequels, season two wasn't as good, particularly since the makers were so foolish as to listen to people who thought Colleen Wing was a good character. She was a weak spot in season one, with her preposterous member of the Hand who just happens---completely independently!--- to fall in love with a billionaire enemy of her denomination. She was unbelievable then. In this season, she plays Darrin to Danny's Samantha, forbidding the use of magic for reasons. Nothing could make her a gripping character after that. If you're going to remake Bewtiched, make some jokes! The fact that she no longer needed to make a living diminishes her nobility in volunteering at a community center. It's not an accident they inadvertently show her dumping Danny the second she doesn't need him any more.
Not having the slightest idea who Misty Knight was, besides a porn star name, nostalgia didn't keep me from noticing she was a zero. Colleen alone was a waste, and Misty alone was a waste, but the two together were worst than a waste, they were a drag.
In addition, backpedaling on Davos' motivations, i.e., rage at being abandoned by Danny and his city destroyed, weakened that character. So, his motivation is that he's just mean, which is dull. So what if it raises dark suspicions Danny and Davos may have had a flexible understanding of chastity as meaning, no girls, if he's fixated on Danny's leaving and Danny is all reluctant to smack him? Listening to fanboys and dumping on Danny for supposed entitlement instead of letting him be an antihero who failed his duty to guard K'un-Lun was a very bad idea. This simultaneously disappears the child abuse/cult indoctrination in a religion THAT REALLY WORKS!!!! in favor of lame self-help cliches and stupid drug addiction parallels.
As to Iron Fist being canceled? The miracle was the first one ever being made at all. Disappeared into a monastery at ten for fifteen years? Everybody can do the math...twenty five year old virgin. There was a reason they hired the Loras Tyrell actor and they should have gone with it.
