What Spin Offs from Supergirl would work? Midvale or Legions or both?

What do you guys think?

And if this his already been discussed and buried in threads, I apologize. I haven't really had time to read a lot of threads in the recent past as our neighborhood has only just now recovered from the effects of Irma. Yeah, there's debris still waiting to be picked up.

No disrespect to fans of the guy who reviews Supergirl on IGN, but I LMAO at his grade for Midvale. It was such a terrific and fun episode and screamed 'Spin Off' to not just many fans, and some reviewers too. The response to the two young Actors have been overwhelmingly positive.

I'd be all for this Spin Off. TBH, When it was time to return to the present, I was kinda mourning the loss of young Kara and Alex. I could totally watch a Spin off dating back to the minute young Kara landed. That way, we'd get Kenny right of the bat. I really liked his character. I think Kenny would be terrific in a young series about high school. Only they'd have get rid of the cliche and OTT jock stuff. It could be like another Riverdale but with a Kryptonian. I honestly think the CW youth market would watch this, as SG is, according to my much more knowledgeable young members of the family, SG cast are old folks. LOL.

As for Legions of Superhero. Other than the fact that there are always talk of over saturation, I think it would work. DC comics are always monetizing their properties in various and endless incarnations. Why not a live tv series too. Again, it would be aimed at a younger demo and general comic book fans.

They already have cast the team, so I'm partially convinced that this is a back door Pilot and they are just waiting for the reaction.

I personally would watch Legions. I love Chris Wood and he has all the qualities of a Lead Actor. If Legions does happen, I just want it to be produced by some fresh blood with a different vision.

So what do you guys think. Either, Or, or Both?
