At the very least, I have to imagine that Arrow fans who don’t watch The Flash and Legends of Tomorrow were confused by a lot of what Black Siren had to say in the midseason premiere.
In fact, all four superhero series on The CW drew lower-than-usual numbers in both demo ratings and viewership in their midseason premiere.
Given that Arrow, The Flash, and Legends of Tomorrow all seem to be more connected than ever in the 2016-2017 TV season, it’s possible that viewers aren’t eager to keep up with all three shows to understand what’s happening in one.
Legends of Tomorrow also experienced a drop for its return to the airwaves in 2017.
