Other mistake: When everything is moving in slow motion, to indicate how fast Black Adam is supposed to be moving, one of the mercenaries throws a grenade from a distance that is shown moving faster than the lightning moving through the bodies. It reaches Adam before the truck he just ripped apart starts to fall.
Suggested correction: The grenade isn't moving faster. Black Adam is moving towards it, he closes the distance. You see it only turns twice before he grabs it and gets to ground level, shove it in the guy's mouth, and then he's back in mid-air in the next shot.
Watch the scene again. Black Adam isn't even in the shot when the grenade is moving faster than everything else. The grenade is moving away from the guy that threw it. He's even moving as fast as the lightning.
Other mistake: The close-up of wine being poured into the glass shows that after reaching about two-thirds full, wine continues to be poured into the glass without increasing its level. (00:04:40)
Other mistake: The men went to Flynn's suburban home, with houses nearby on both sides (and probably on the opposite side of the street), at night and many loud gunshots were made inside as well as outside, but no neighbors turned on lights or were disturbed. Dogs did not even start barking until the shooting stopped and Flynn was driving away. Even if neighbors heard but did not want to risk getting killed, the dogs should have started barking at the first sound of gunfire (if not when the men arrived). (00:26:08 - 00:27:49)
Other mistake: Two goons almost caught up to Jimmy's Suburban when Natasha was driving. It isn't clear what the distance was between the vehicles, but close enough to see the other's vehicle. Natasha slowed down so that she could roll out of the driver's side "unnoticed" - and she somehow managed to do so. (00:47:18)
Other mistake: Whilst questioning Dani, Carmichael gets a text alert and immediately takes out his phone and looks at the text. The time on his phone is 10:48, but the message is shown to have been received at 10:45. Three minutes did not pass in between the time he got the text alert and the time he looked at the message, only a couple of seconds had passed. (00:51:20)
Other mistake: The woman told James that Salim Mohsin was 42 and conducted research at a private laboratory. The part about Mohsin being "professor emeritus" of virology at Humboldt-Universitat seems contrary to his age (42) and the common meaning of "professor emeritus", which is retired and collecting a pension. It might also be unusual for a tenured professor conducting research at a university to leave in order to conduct research at a private lab. "Other" mistake because not sure of emeritus in Germany.

Other mistake: It didn't make sense Catherine was a Catholic preacher but worked at The First Baptist [Protestant] Community Church" and drove a van with the same on it. (00:31:00)
Other mistake: It didn't make sense that the "fighters" were given protective gear (vests, boots, arm and elbow pads, etc.) if death was an expected outcome. Also, a private "for profit" prison is paid per number of inmates housed, so deaths in The Dungeon would reduce profits and would be avoided, not encouraged. (00:34:00)
Other mistake: Visser was face-to-face with Omar when she shot him in the neck (looked more like it would be in his mouth before the camera shift) yet she did not get any blood splatter on her shooting hand, face, or clothes. There also wasn't much blood on Omar considering he was hit with a near-contact if not actual contact shot. (00:45:41 - 00:47:12)
