Since I don't see any one post that I can "this".
Supergirl starts off fairly weak. It starts off being with some heavy-handed "girl power" and the black "James Olson" will make you take a step back out of surprise. The effects aren't perfect, and the plots are pretty simple, all adding up to something that you will either like, be passive towards, or it will utterly put you off on it not being the show for you.
However, as it progresses, it does become something that doesn't hurt to watch. For the most part, it's fun and light-hearted, and on its way to finding it's stride, once it gets to Martian Manhunter, it starts doing some out of this world stuff, and while I know somehow there are waifufags about the actress, I think she pulls off Supergirl really well.
It's really a show that rewards sticking with it, and if I had to rank it among the other cape shows, it'd be above Arrow, and between LoT and Flash, but still in its own camp. Not perfect, but still interesting and enjoyable to watch, if you let it be.>>82389278
Then with Gotham. Absolutely, is it good. It's hardly a superhero show in the same sense as the CW shows and Supergirl, but, in its own right it's absolutely wonderful as you go through it, being a great treat for people who are willing to have a little fun with their darkness. Another show that really rewards the people who stick with it. I don't know why people feel that you have to shit on it to like everything else, or you have to shit on everything else in-order to like it, but it's a good show to watch, and has moments that'll keep you at the edge of your seat. If I had to compare it among the other shows, though, I could argue it's better than all of them, but it's hardly even the same genre, so it's apples and oranges, and shows like Flash and Supergirl delivered more on the "fantastical superpowers" aspects that I enjoy seeing and generally get hyped for.
