I'm still hoping the cancellation of Luke Cage and Iron Fist means we finally get a Power Man and Iron Fist series.

As for Daredevil, season 3 had a satisfying end to the series. I'm sure they can do another story (probably something with Silvermane, Owl, or Typhoid Mary as the villain) but it's not necessary as they've already done every major Daredevil arc in the comics. The only thing really left for Daredevil is the death of Karen Page, which seems too small to build a season around.

Sorry to hear that. I liked Luke Cage.

Iron Fist and Luke Cage were just simply not that great as a standalone series. I could see them doing a heroes for hires show or something else. As for Daredevil I think to squeeze out 3 seasons was enough. We got to see The Punisher, Elektra, The Hand, Kingpin, and Bullseye. What else is left? I really enjoyed Season 1 of Jessica Jones but the second season was a bit of a chore to watch. I don't think this is a bad thing if it means more Punisher seasons and possibly some new characters such as Moon Knight, Blade, and Ghost Rider.
