No reason to just insert Wonder Woman in everywhere. You are just complaining. Face it, she is not as popular as batman and superman. I would prefer her to have her own movie than in this one, let superman and batman do their thing. And not all dc hero movies need to stop because they didnt do a Wonder Woman one. She really doesn't even need one. Now I expect people to yell at me but everything I said is true, she's not as popular and doesn't need to be in this movie, there's no reason for her too. It's not the comics.
The exact same thing could be said for characters like Thor or Captain America, but they got solo films, right?
