The Defenders was pretty good to my standards despite being only 8 episodes. I really liked the dynamic between each characters but wish there was more screen time with Luke and Iron Fist together. Overall, hopefully the second installment gets better since we were left on a "WTF Moment" towards the end.
I think they might be working on a spin off with Detective Knight and Colleen (Daughters of the Dragon). I also can't wait for The Punisher to arrive on Netflix, that's going to be one brutal/gruesome show.
