Supergirl is fun but extremely stupid.
Marvel has a lock on the tv shows as much or more than they've had a lock on films since Nolan's Batman trilogy ended. Agents of SHIELD and Agent Carter are both just really well made. Shield has some seriously corny moments, especially in season 1, but it's grown more and more cinematic in quality and scope. Agent Carter is classy AF.
Daredevil and JJ are great, and Luke Cage was pretty good.
Meanwhile DC has all those CW shows and Gotham, all of which -- though fun -- are more cheese than meat. Gotham is probably the best and even that is stupid beyond compare on a regular basis.
