I've been watching a little "Supergirl" over the past few days. Years ago I bought Seasons 1-3 and 5 on DVD as they were coming out, however when I got to 3 I was finding the series wasn't keeping my interest. Then I think I didn't buy 4 because I didn't see it in stores at the time and I figured I'd pick it up later. Also I was getting annoyed with the crossover episodes because they would only have the Supergirl episode of the crossover on the DVD and none of the others, so it was like Part 1 or Part 4 of a story.
Of course I just recently found out that in Season 4, Nicole Maines was added to the cast as Dreamer/Nia Nals, the first transgender superhero.
