Defender roles in a nutshell

Jessica Jones = The Annoying Bitch
Luke Cage = The Emotionless Brute
Danny Rand = The Dumbest Iron First (mentioned in episode 4 if I recall)
Matt Murdock = The Elektra Fetish

So Hand boss lady says the Black Sky is more powerful than you ever know yet Elektra seems to fight as before and only remotely overpowering her opponents (minus when Matt goes emo on her and not fighting his normal self). The fight choreography is mediocre and seemed overdone to the point where it doesn't amaze you much if at all since the start of it in DD S1. They also went full Jason Bourne in episode 7 with all the shaking ass camera movements to simulate a horrible fight. Maybe too many heroes involved or that they keep sending basic bitches to fight heroes with powers and still can't kill them.
