hmm... i prefer the Supergirl that arrives on Earth as a teen/20's that doesn't like or trust humans much and doesn't know how nor want to 'fit in' not a homebody nerdlinger, and a Supergirl that has her own House of El uniform/costume not one her friend had to sew...
+ muscular/non nerdy 'James' Olsen? really? bah
I can see it being popular regardless of ^^^^^ though
