The DC comics that these television shows draw on as source material has a history of “Crisis” events, wherein different universes are split apart from one another or merged together; typically, it’s an attempt to streamline continuity, although it’s debatable as to whether or not it really does make things simpler. As such, then, there are a vocal group who are clamouring for a similar such event to occur now, moving Supergirl into the same reality as The Flash and Arrow, positing that the slated crossover special should be used to reset Supergirl, and essentially reboot it to better fit with the other superhero programmes currently airing on the CW.
Despite now being in a position where it has to move networks, Supergirl’s viewership on CBS did in fact far outstrip the ratings that The Flash maintains on the CW; this is, of course, because CBS itself has a far wider reach than the CW, but it’s also a certainty that the CW is hoping that a large number of these viewers follow the show to the CW. It makes little sense, then, to try and change what is essentially the more popular show to ‘fit’ the more niche one – why would the CW consciously alienate the fans they’re trying to attract?
A new Yahoo article from me, all about why I think a Supergirl reboot to fit in with Arrow and The Flash is, essentially, a terrible idea.
