Yeah, that sucks.
Doesn't mean the show can't be good or great though. Supergirl S4, all of Legends are good examples of this.
most likely a location change
Stargirl films around Atlanta like Black Lightning. No reason to assume a location change like when Supergirl moved from LA to Vancouver.
longer seasons which increase the episode count for no reason
You're kind of throwing out a lot of baseless stuff. Why are we assuming the series won't continue to be a smaller episode count?
Black Lightning ranges from 13-16 episodes. Legends S3 is one of the best seasons of superhero television and was 18 episodes. Most recent season was 15 episodes and was great. There's no reason to assume Stargirl will be change to a 22-episode season, especially given how much superhero stuff CW now has on its plate.
inevitable crossovers with shows I don't watch
I mean, they were already hoping to make that happen in the future either way.
But I don't see Stargirl taking part in the huge yearly crossovers where you
need to watch the other shows if it continues to air outside of the standard schedule.
That's just some of things I'm worried about happening. Titans is really the DC Universes only bad spot (Swamp Thing kind of too, but that's already gone so whatever.) which gives it a much higher batting average than The CW
Honestly, the batting average is very similar overall. Especially if you're just comparing at the live action shows, which I mentioned in my last post.
