All four of the DC comic book TV show adaptations co-created by Greg Berlanti - Arrow, The Flash, Legends of Tomorrow and Supergirl - now call The CW their home, with Supergirl having moved to the network after its freshman season aired on CBS instead. The Supergirl season 2 premiere - titled "The Adventures of Supergirl" - does contain a few in-show references to the series' change in networks (see: a "new" headquarters revealed for the DEO). Similarly, the show's season 2 opening sequence contains a few different clips compared to its season 1 predecessor - with the brief glimpse at this past spring's Supergirl/The Flash crossover, "Worlds Finest", arguably being the most noteworthy addition to the opening.
Supergirl's producers previously said that the show would feel more like part of a larger comic book TV show universe in its second season and so much held true for "The Adventures of Supergirl"; in between a tweaked opening that also includes J'onn J'onzz (David Harewood) appearing in his proper Martian Manhunter form, as well as the introduction of Tyler Hoechlin as the show's version of Superman. The show also started off its second season on the right foot in the ratings department, reaching viewership levels that The CW hasn't seen in Supergirl's timeslot for a while.
Per The Wrap, the Supergirl season 2 premiere attracted 3.02 million total viewers and achieved a 1.1 rating in the 18-49 demographic. Those are the best numbers that a show on The CW has done in Supergirl's Monday evening timeslot since an episode of Gossip Girl that aired back in December of 2008. To compare to the recent premieres of other DC TV shows on The CW, The Flash's season 3 premiere episode "Flashpoint" attracted 3.1 million viewers during its initial broadcast, whereas the Arrow season 5 premiere episode "Legacy" brought in 1.9 million viewers.
Generally speaking, The CW's Arroverse TV shows have never been major ratings draws compared to other networks' programming - making the turnout for Supergirl's season 2 premiere a perfectly solid start to its time at its new home. It remains to be seen how Legends of Tomorrow fares ratings-wise when its own season 2 premiere airs in a couple days (from the time of writing this); but based on the turnout for the other three DC TV shows on the network, it should do similar numbers - what with the Arrowverse's core fanbase seemingly holding steady, in terms of its overall size.
Arguably, the real test for the Arrowverse in general will come over the television season ahead, given all of the major "events" on the horizon. Those include: another Supergirl/The Flash crossover in the form of a musical episode, the introduction of the Justice Society of America on Legends of Tomorrow season 2, and a four-way crossover between The CW's DC TV shows that pits their superheroes against a major extraterrestrial threat. So long as the ratings for those events (and the respective Arrowverse TV series) continue to hold steady and/or increase, then Berlanti's DC television universe and Supergirl alike should remain in fighting shape.
Supergirl continues Monday October 17 with ‘The Last Children of Krypton’ at 8pm on The CW.
