I've watched it and so far have been mostly pleasantly surprised. The series has promise. I just hope they don't mess it up. I suspect the Jonathan character will eventually get at least some powers. I'm not really fond of the Jordan character so far. Hopefully how they write that character will improve. Or perhaps part of the reason is the actor playing Jordan. I really haven't gotten into watching the various CW series. I never got around to watching Arrow. I stopped watching the Supergirl series i believe after season two or maybe a bit before the season end. I don't remember. . So i probably won't notice if there are any vague crossover mentions. By they way, are there any particular episodes in the later Supergirl seasons that are good and worth watching? Any Superman appearances in either Arrow or Supergirl? Are those series on one of the streaming services?
