I just used those movies as examples, but you make good points.
It's kinda disappointing what happened with Cyborg, considering he's the only guy in the JL movie who had an actual emotional journey in that movie (I'm surprised Snyder could pull that off), plus he's the most prominent African-American superhero in DC.
I'm interested in seeing how Supergirl fits into Flash. At least we'll be getting some part of the Superman universe, right?
