Re: Should they introduce Kara Zor-El in the sequels?
Yes. Make her a young child; 12, 13, 14...around that age who appears as a Kryptonian survivor in the sequel.
The writers did want to explore that angle of Kryptonian survivors.
Id like her to be someone Superman has to rescue in the sequel....but in the film after that, when shes around 16/17, she can be Supergirl.
