Should new showrunners be brought in?

Yes, I agree - I certainly want to keep the concept of the "Supergirl Team" (which I love) in the show. But in my opinion only a few "core members" are necessary in each story.
In my own fan fiction stories, they're Alex, Lena, Winn, and Brainy. I also have Dick (Malverne) and Susan (Ramirez) on the Team, but they are more on the periphery. And then I have a few "honorary members" (Cat Grant is one) who come and go, but are not in every story. And in every story, Kara is the unquestioned "leader" of the Team - and gets the lion's share of the action sequences (and the face-to-face confrontations with the villains). Ideally, I'd like to see something like that on the TV show, too!

Im getting pretty tired of the Supergirl team, as it was in Season 1....no problem, they could still do that. But now you have 3 Superheroes and Alex who Im surprised have not given her superpowers somehow.....the secondary characters have grown to a number that has now moved into Supergirls realm in time and power....Im not ok with that.

Honestly, I have no clue who is to blame, all I know when AK was here ( and this by no means means I want him back, it is simply an observation) when he was onboard there was a different vibe in presenting Supergirl and the time given to her. I think that is why a lot of the criticism has fallen to the showrunners. Im sure they are wonderful people, but that has nothing to do with their ability to show Supergirl in a way that is, for lack of a better word, "super". IMO....there was a start this season with the super montage, and then it was like.....ok we've shown she is super.....moving on to EVERYONE else....lol. AK understood the Super, in Supergirl....my hope is that we get that back in these last few episodes and go back to a more Season 1 balance, along with the cohesive writing of this season.

I couldn't have said it better. I watch this show for SUPERGIRL. Nobody else. I understood they wanted to flesh out J'onn and Alex, more, after season 1 (which was a noble goal, but that leads me to a whole different rant about how season 2 was executed). But they continue to add more characters, and give them equal focus to the primary protagonist.

The writing HAS been really cohesive, this year. My problem with it is that they seem to have said "this is the social/cultural/political allegory we want to tell", and then tried to figure out how Supergirl fits into that, instead of starting with what Kara's journey for the season should be and working outward, organically, from there. Due to that, she had so little focus in the first half of the season, and while it's been better in the back half, she continues to be pushed aside.

But I suspect that contractually they have painted themselves into a corner and may be required to write these characters into more episodes than we the fans find necessary.

Yet they continue to buy more paint because they keep bringing more regular characters in to require more time spent away from Kara.

I loved the concept of "stronger together" that they built around Kara in Season 1. But, that was when together meant four-five other characters helping Kara rather than an entire community of superheroes and tertiary humans. Nia and Brainy's budding romance, Alex's ongoing plight at motherhood/finding a new love interest and James and Lena's on-again off again affair is taking the concept of stronger together a bit too literally. None of it has anything to do with showcasing our titular character, Supergirl and it's boring as all get out.

The one thing that I really liked about the first half of last season was that it really explored Kara - aside from the Alex relationship drama that went on. I know it was a bit dark, but Kara's life hasn't been a hotbed of roses and sunshine so it made sense. This season's story with the idea of the city turning their backs on aliens was really a great opportunity to connect and expand on the emotional turmoil that they started last season and suddenly dropped half-way through. But, instead, they use it to highlight the issue itself, J'onn's emotional turmoil and Nia's, a new character, emergence into a superhero.

With the improvement in writing cohesiveness, I think that perhaps they have a writing staff that might be capable of doing Kara's story some justice. We just need the leadership to steer them in the right direction.

Argee with all of this, but in particular, your comment regarding paint illustrates the absurdity brilliantly.
