The thread is a fair criticism on the showrunners. I softened some language but I’ll let it continue. I am not beholden to them but I have met them a few times in person and they are very sweet people. Ali Adler was incredible as well. That’s all I will say but please continue with care on this topic.
First off, thank you for leaving this topic open.
I would like to point out that, I don't think anyone is saying the showrunners aren't wonderful people. I think it's great that they want to broach gun control, immigration and refugees, and introduce our first Trans superhero. There are those who say it should be left out of entertainment, but I'm not one of them, because comics, along with comic based TV, has always served as a commentary, and these are important topics, in today's world.
I think the primary issue is the execution. As I said earlier, it feels like they are broaching these topics, then trying to figure out, after the fact, how Kara and Supergirl fit into it. I think Kara's journey and arc need to be established first and foremost, so a story can organically build from that. Then you can build the arcs of the supporting cast, from there. This way, Kara's story and journey is always first and foremost.
As it stands, it rarely feels like Kara has a Journey in this season. Alex has her journey, running the DEO, adapting to Hailey at the DEO, losing her memory, trying to adopt. J'onn has a journey, becoming a P.I. Nia and Brainy have journeys, this season, with Nia accepting her powers, Brainy adapting to the 21st century, and the two's seemingly teased romance. Even Lena and James, with their somewhat minimal screentime, have a journey this season (more so with Lena, pursuing her experiments and dumping James). But Kara? She literally just feels like a supporting character in everyone else's story. Especially Alex's and Nia's. Kara's biggest story this season is "Alex was mind-wiped". Which, again, feels more like an Alex story, than anything.
And if the showrunners had been building a story, organically, working outward with Kara as the focus, that wouldn't be an issue.
My other big issue is that they currently don't seem all that adept at planning the long game, story arc wise, based on the back half of season 3. I want season 4 to prove me wrong, but it just hasn't.
So yeah...while I hold no ill will towards any of the showrunners on a personal level...yes, I believe new showrunners should be brought in. I'd go so far as to say the whole writing room could use an overhaul. We're 12 episodes into the season, with 10 left, and I can honestly say there are only 3 episodes worth rewatching, for me. That's not good, from a guy who would watch season's 1-2 over and over.
