Earlier Thursday, the CW has announced that not only did they secure the rights to Supergirl, but they’re going to have a crossover episode between that, Arrow, The Flash, and Legends of Tomorrow. This is interesting, however what will the execution turn out to be like? Also, the fact that the CW has not only snagged a previously canceled show…could this bring back hope for Constantine, which was canceled by NBC, last year? Anyway, back to the topic at hand; this is not the first time CW has featured crossover episodes. They have once did it with the Flash and Supergirl, and I believe Arrow and Flash had one too. That said, I need to sit down and catch these shows, given I have given praise to them for the most part based on what I have seen so far.
