Other mistake: After realising they can track the mother box, Batman says they have to go back to his base to use one of his satellites to track it, and they all do so. Which completely ignores the fact that Cyborg could easily access the satellite feed directly using his abilities and display it to the others on any nearby screen in Star Labs.
Suggested correction: Just because he had many options available to him, does not mean that the option which he chose was wrong.
Alfred Pennyworth: How do you know your team's strong enough? 'Cause if you can't bring down the charging bull, then don't wave the red cape at it.
Trivia: Despite his directorial credits, Zack Snyder never actually watched Justice League (2017). Christopher Nolan and Snyder's wife, producer Deborah Snyder, told him not to go and see Joss Whedon's finished production of the movie, because, according to a new report in Vanity Fair, the pair told him that the final result would "break his heart."
Question: When did Martian Manhunter get to Earth, why did he assume Martha Kent's identity, and where is she during Justice League?
Answer: Martian Manhunter is played by Harry Lennix, who also plays General Swanwick, a character who appears in Man of Steel and Batman v Superman (and we can see he transforms back into Swanwick he leaves), revealing that Swanwick was Martian Manhunter the whole time, so the indication is he got to Earth before Man of Steel. He assumed Martha's identity to speak with Lois, specifically to have a heart to heart with her as she is depressed due to Clark's death. Martha is present every other time we see her, when she leaves the Kent home at the beginning and when she reunites with Clark later on. This scene was the only time Martian Manhunter used her identity.
