first two season of DD were pretty good from what I remember
JJ season 1 was fantastic too, haven't seen 2 yet.
But really all it is most likely is Netflix losing the license. They aren't getting any more Marvel movies on there either, as Disney is prepping for their streaming service.
JJ season 2 isnt worth watching. Its on the same level as Luke Cage and Iron Fist. If thought those were decent you may like it. I thought it was boring as fuck.
Its much worse than any other Netflix marvel show ---
