Just to clear up some facts about this all...I stated earlier that this wasn't up to Netflix, turns out that wasn't correct entirely.
These shows are insanely expensive to produce, and for the most part have been pretty poor. Initially viewership was high despite this, but as time has gone on, viewership has sunk while costs have risen.
Netflix was willing to keep the shows going, had Disney allowed them to shorten the seasons to 6-8 Episodes, and reduce costs. Disney however, said no dice.
So there you have it. The Marvel Netflix shows weren't very good, didn't have a huge viewership, and were insanely expensive to produce. Netflix tried to keep them on by reducing the number of episodes thereby reducing the overall production costs, and Disney said Nah.
FWIW, these violent iterations of Marvel will 100% not be on the Disney OTT service. So they are done.
