I thought Luke Cage's first season was sort of a mixed bag. There were things I liked (the setting, and Luke himself, since Mike Colter is a great screen presence) and things I didn't (I cannot stand him being paired up with Rosario Dawson's Claire- the two have negative chemistry and don't make sense together as a couple, plus the main villain in the end wasn't very interesting), so the second season has things it can definitely improve on. Misty Knight's back now with a bionic arm, and I heard that Iron Fist is going to show up. Alfre Woodard's character looks to still be causing trouble and a new villain named Bushmaster challenges Luke's invincibility somehow. Here's hoping it all comes together a lot better than Jessica Jones's second season did.
