Honestly, I had forgotten that this was in development. But now that I’ve seen the trailer, I am greatly looking forward to this. At first, I didn’t understand why they wouldn’t want to make this a part of the larger Arrowverse, but now I get it. They have a contained story that they want to tell, and putting it in the larger universe will muddy the waters a bit. Besides, they’ve established the Multiverse. It would be incredibly easy if they ever wanted to in the future to just say that Black Lightning is on another Earth.
