It is impossible to make every fanbase happy....but IMO, you should at the least do your best to keep your core fanbase, that fanbase that has been here since the pilot somewhat happy for the most part. This is a story about Kara Zor-el from Krypton and her adopted family Alex. That is the base from which every thing should happen. The base "places" where all of this happens is Catco, the DEO and Kara's apartment. Whomever comes into Kara's life should and will get the majority of the screen time, those people that are closest to her. That being Alex, Cat, Jonn, Winn, James (not Guardian) JAMES, Mon-el and Lena. Not necessarily in that order all the time, whatever the story line needs. HOWEVER, KARA/SUPERGIRL should be at the center of each of those. Now we know that Calista will not be a main cast member again this next season, and that is ok with me,and I'm a huge Cat fan...Now, IMO, if they do those episodes like that did last year where it focuses on 1 of the characters back stories yet still keeps Kara at the center, then cool....I wasn't a huge fan of "Child's Play" but the dynamics of the story were fantastic, I loved "Stranger from another planet" I thought it was beautifully written, beautifully acted and one of the best of both seasons. In both we learned so much about Winn and Jonn, and yet in both Kara was front and center. This season we have not had that, anytime it was another character centered episode that character took front and center and we barely had Kara in the episode. The episodes themselves were not bad at all, "City Of Lost Children" was not a bad episode at all, it simply didn't have Kara in it....(now I know that part of that I'm sure was Melissa not being on set possibly), but it is her show, and therefore all 22-23 episodes she should be front and center. We got that in "Luthors", we got it (I didn't think so at first, but with more viewings) in "Darkest Places" with the big introduction of Guardian. So, next season I hope they don't try to continue 4 to 5 different story lines in every single episode. It got really tiring to watch and keep up with, and it seemed like some of the plots were just thrown in so that we could see this couple or that couple. ie: Lyra and Winn....don't like it, it needs to go.
Bottom line is this, there is going to be a "shipping" group that is pissed off, plain and simple. I think they are realizing this. But for #Sanvers shippers to think that Maggie is going to garner more screen time, and that Floriana is happy to hang out in Vancouver for a scene here or there is "floating down the river of de"Nile"..." To me I would much rather have a few episodes maybe 3 that follow the line of "Alex". With Guardian, it IMO would be very hard to give Maggie much in the way of the "street wise crime fighter". I actually think that is sad, I would much rather have that scenario, but alas that isn't one of the big changes. I think the #Sanvers bunch needs to be happy with what they will receive, because it is a bad place of a lot more than the #Supercorp shippers are going to get.
They will never get the big change of a Kara/Lena lovefest, and unfortunately for this series they are extremely loud and extremely rude. And unfortunately we will probably have to weather that hurricane. The next BIG CHANGE I hope we get is that Mon-el is a full fledged superhero, he and Kara can have a happy reunion, and even a couple of Legion centered episodes, but may they have their lovey times together few and far between.
I actually think the #Karamel shippers would be ok with that. Though there are a few that won't, for the most part I think they will be fine.
