I will say that Typhoid Mary was ALMOST, but not quite, a scene-stealing character similar to and on par with The Punisher. Actually her story arc was kind of similar to the Punisher's in Daredevil season 2, which kind of detracts from it.
The music was terrible.
Really now that I think of it the main story of the season seems like they tried to take the elements that 'worked' from the other series and Frankenstein's monster them into this show.
Joy was not good as the villain. Her character changed completely from the first season. And then changed AGAIN halfway through this season. And Davos...his switch to psychopath was sudden and dumb.
One of the very few redeeming qualities about the show was that Davos was kind of right at first. Danny was an outsider that showed up in Kun-lun, trained with everyone else, beat the man who thought he was destined to protect the land as the Iron Fist, became the Iron Fist himself and then abandoned Kun-lun to go be a billionaire in the West. I mean, Danny didn't deserve to be the Iron Fist, and the consequences showed it. That was a great conflict right there. But then they fuck it up by making the power of the Iron Fist similar to holding the One Right in LOTR.
I wish Colleen becoming the Iron Fist meant that they were phasing Finn Jones out of the show. A show of just Colleen Wing, Misty Knight and maybe Typhoid Mary would be much, MUCH more entertaining.
