That probably means there isn’t going to be a crossover event between the shows, but considering the time gap between them, that never seemed like a possibility to begin with.
With David S. Goyer writing the pilot and executive producing the series, fans of Man Of Steel and The Dark Knight Trilogy will hopefully take a liking to Krypton.
The fact that the series seems to adopt a darker tone closer to the cinematic universe as opposed to Supergirl and the brighter Arrow-verse of The CW is a nice change of pace.
Still, it would be cool to see if the two shows could work out some sort of subtle way to reference each other, considering it’s not every day two Superman related shows are on television at the same time.
