First off and most importantly, we are getting more episodes. I loved this show. The character was bright, optimistic, fierce, and learning the ropes. The relationships between the characters were the backbone of the show. Kara and Alex. Kara and Winn. Kara and Cat. Kara and Jimmy. Kara and Hank. They all had heartfelt moments and character arcs. We had action. We had it all as Supergirl fans. And I loved it. The show could have been canceled. It wasn't. That is the most important part of this announcement. We are getting more episodes.
Now, maybe there is an old-school feeling that moving from CBS to The CW is a demotion of sorts, a loss of prestige. But, as been said ad nauseum, the show 'feels' more like a CW show than a CBS show.
And, of course, it opens up the possibilities of more crossovers. Certainly, a time/space warp could lead to a DCLOT crossover.
But there are some concerns.
For one, the production has fled to Vancouver. So the whole feel of the show being in Hollywood/California is going to be gone.
Second, the reason CBS let the show go was that it was too expensive to produce. It is doubtful/impossible that the CW will be able to front the budget of last season. So will there be a drop in the effects. Will stories be written differently, avoiding big action sequences. Will there still be wire fighting? That said, I think the Flash has done a fine job with effects, so maybe it won't be noticeable?
I am not an accountant. I don't understand production budgets. But maybe the $3million dollar 'license fee' per episode will disappear since Warner Brothers owns CW. Maybe that money can be shunted to the production? Of course, the show has to make money for the network so maybe cuts are coming.
Lastly, will the very structure/cast of the show change? Will Kara be in a different city? Maybe her new role in CatCo takes her away from National City? Will David Harewood? Will last season be 'forgotten'? Will we pick up were last season ended, with the mysterious pod?
I have faith that the production company and Greg Berlanti and Ali Adler will do the show right. They clearly love it.
But the unknown is scary. Let's be optimistic.
One thing we don't need to worry about is the Alex/Kara relationship disappearing. Both Chyler Leigh and Melissa Benoist hit social media last night to thank CBS and promote the next season.
