I think they should have added in maybe another villain or henchman of Kilgrave to give the show more substance. It just drags along at times... I feel like they make it for Netflix, they plan on people binge watching, and so each episode doesn't stand alone as well as most regular TV shows.
I'm excited for the Defenders mash up. I think Jessica Jones will do better when she has partners and other plot lines to keep it more exciting. Really enjoyed having Luke Cage in the show
