Goofs

When Cyborg tries to access the Motherbox to close the Boom Tubes, it blows up in his hand. Yet in the very next scene it is back in his hand completely intact.

(at around 1h 12 mins) When Green Lantern flies off to catch the falling humans that are coming through Cyborg's Boom Tubes, in one shot Shazam is shown where Superman should be.

Green Lantern's right arm is broken and he encases his arm with a cast using the power of his ring. While doing so, his ring changes place from his right hand to his left hand. In the next scene when he tries to lead the other heroes, his ring disappears when he clears his throat and then reappears again after a while.

Wonder Woman's ice cream cone disappears between shots when the Parademons attack DC.

When Batman is holding DeSaad by the throat, the ligature on the left side between his upper and lower lips is missing.

When the President speaks at the end, the flags hanging on their side have the stars on the right. This never happens. When put on their side like that the flag is flipped as the stars are always on the left.

Batman unmasks himself in front of Hal Jordan, why does he do this??? This is not only extremely stupid but could reveal his identity to active security Camaras, other people, and any satellite in the sky. He is also Bruce Wayne, this could expose him, his company and put his allies and family in great danger. He has more to lose then anybody. No superhero would willingly expose there identity like this, it's just not done.

Batman needed to look like a civilian to be kidnapped and brought to Superman. The Parademons likely would keep attacking him if they recognized him as Batman.

When Shazam says his own name to introduce himself to the other heroes, the lightning that transforms him from Billy Batson to Shazam, and vice versa, does not strike. However in the New 52 continuity (upon which this film is based), the word "SHAZAM" only works when he intends for it to. Otherwise he can say it without effect. This was necessary when they changed the character's name from Captain Marvel.

Why does Darkseid on of the most powerful characters in the DC universe leave his eyes open as weak spot??? Darkseid is intelligent, and very powerful. If his eyes were his weakness, shouldn't he have been wearing some king of eye protection over them. This makes no sense.

Darkseid is incredibly confident in his abilities and resources. To wear eye protection would mean acknowledging the fact that he has a weakness. Darkseid also needs a full range of vision to use his Omega Beams which is one of his strongest attacks.

How is The Flash able to take out one of Darkseids eyes with a crowbar??? Everyone has either magical abilities or superpowers, and they don't seem to affect Darkseid much. This makes no sense, and is a definite mistake.

Darkseid's eye only explodes after Shazam conducts his godly lightning through the metal crowbar.

Why doesn't Hal Jordans ring not have healing abilities??? This is one of the most powerful weapons in the DC universe, it should easily heal it's ring bearer and maybe even other people. Yet it doesn't. This is a problem in a lot of the movies that feature the Green Lanterns, but it is a mistake here as this could have healed Hal and it could have been far more useful in the final.

Writers change the powers of characters when doing adaptations. Sometimes Wonder Woman can't fly and sometimes Shazam always transforms when he says his name. This version of Hal cannot heal himself with his ring.

When Diana is coming out of the white house, she appears to go through the front gate. This is not a superpower of Wonder women. Clearly the animators made a mistake, it's there but you have to look close, it goes by quick.

We never see how Batman frees Superman from the Parademon infection. One moment he's trying to kill Batman, the next they are both coming out of the Boom Tube and they are completely fine. Not to mention they are now wearing some kind of armor chest plates that are never explained.

Right before the Parademons attack, Steve pulls Wonder Woman away from the ice cream stand saying that the President is waiting for them. Yet in Wonder Woman's next scene after the Parademons attack she has to fly up to Air Force One to rescue the President and the First Lady. How could the President be waiting for them if he was on a plane in flight?

Cyborg has to make a direct interface connection with the motherbox in order to close the Boom Tubes. Yet at the end he doesn't need it to reopen them and bring all the normal people back to Earth?

Justice League: The Flashpoint Paradox (2013) was meant to lead into this film as the start of a new cinematic universe. Justice League Dark: Apokolips War (2020), Suicide Squad: Hell to Pay (2018), and Justice League: Crisis on Infinite Earths - Part Three (2024) confirm this as Barry remembers resetting the universe multiple times. However, Batman and Flash meet for the first time in this film even though both of them knew each other and their respective secret identities at the end of Justice League: The Flashpoint Paradox (2013).

During the final battle after when Darkseid's eyes were taken out, when Shazam uses his lighting on him,he was shown to have his left eye intact despite being gouged out.
