Pretty much all of The CW’s Arrow-verse shows have genuinely embraced a certain degree of self-aware campiness, and that has resulted in plenty of fantastically meta moments over the course of the last few years that fans have really responded well to.
It is not terribly surprising to learn that the folks behind Supergirl have an interest in getting Dean Cain and Teri Hatcher back together on the small screen, which was revealed at a recent press event (via CBR).
