Again. Soldiers. Bullets. Granades. Lots of them. Real danger.
Then show her getting hit by bullets and getting actually hurt instead of never getting hurt. The MCU movies weren't afraid to hurt Cap, Ant-Man, Iron Man or Spider-Man.
They understandibly didn't want to take half an hour for that flashback, so it's obviously condensed. But it took the armies of Atlantis, Themyscira, the "tribes of man", Green Lanterns, and the Greek Gods, including Ares.
The combined armies weren't doing any damage to him, just cannon fodder to occupy his Parademons. The Lantern did nothing to him but die, the only damage we saw done to him was Zeus' lightning bolt.
Also see how easy he had it taking the Mother Boxes from the Amazons and Atlanteans, and he was established as pretty damn powerful.
The Amazons aren't that tough, seeing how a WWI Group of Germans killed them in combat. We don't know how tough Atlanteans are.
In-universe, it could be explained with Superman coming back from death more powerful than before.
I can see why some think that, but nothing suggests it.
I guess whether they accomplished it is a matter of taste, so debating it is moot without established criteria.
I suppose.
