Although Marvel's last Netflix series, Iron Fist, was the comic house's first real dud in a long stretch, the street-level team-up The Defenders still looks promising. The series features Iron Fist (played by Finn Jones, previously the gay Ser Loras on Game of Thrones), Daredevil (Charlie Cox), Luke Cage (Mike Colter) and our favorite Marvel cinematic universe heroine Jessica Jones (Krysten Ritter) teaming up to take down the bad guys. The new episodes drop Friday, and we're really hoping we get better acquainted with Daredevil's abs.
