That wasn't it.
Just didn't work.
Marvel usually tight with that in the past but in-house politics and Feige losing power etc etc messed up the flow. After some realignment and Feige back in power they reviewed EVERYTHING scaled back, cancelled and cut, fired, rehired got real showrunners for Echo and EVERYTHING ELSE.
Luckily they were able to salvage Echo with editing and reshoots and that helped in a way save Daredevil too.
We been broke all that down.
