Daredevil. Jessica Jones. Luke Cage. Iron Fist. Yeah, New York won’t know what hit it. Yes, “Iron Fist” will premiere before “The Defenders,” but really, this is the culmination of all the Marvel Netflix series so far, and having our favorite characters finally fight side-by-side (and no doubt bicker with each other) promises to be entertaining as hell. We’re also intrigued by Sigourney Weaver’s casting as someone who is “very smart” and “very in charge.” Perhaps villainy is in her future?
