I'd prefer a JSA film over a JLA film for several reasons:
- There has already been a JL series and JLU. I know the JLU expanded and featured some JSA members, but it just isn't the same.
- Some members of the JLA have already had several media exposure like shows, movies, games, etc.
- It would help expose some perhaps you could say "not as commonly known" heroes to the average public. Let's face it...a non comic fan wouldn't know about any the JSA members most likely compared to JLA members.
Also, I just really want to see something JSA-related. Could be because I'm loving the newest JSA title and that I've been wanting to know more about some of their members and have kept my eye on some for a good while, but...it would be a better idea than a JLA film.
