Corrected entry: In this version, Flash does not carry the hostages to safety; he is sort of a cheerleader/crossing guard appearing in different spots of the stairs asking if they are OK and saying "This way." What sort of role in a battle is that? How does that help in any way? It's not that he's afraid of battle like in Whedon's version and he fights nobody on the path. (01:58:25)
Corrected entry: In this version, Queen Hippolyta whispers "Return to me, Diana" as she shoots the arrow, as opposed to "Listen to me, Diana" in Whedon's version. Whedon's line made sense, since it was a warning, this does not, since Diana never comes back to Themyscira nor she is supposed to, being busy thwarting the invasion in the Land of Men. There's no reason why the Queen would say that line. (00:43:10)
Correction: It wasn't the Queen telling Diana to come home at that moment, but a way of saying "survive the war." This would be like a mother telling her soldier son as he goes to war to return home.
Under normal circumstances yes, but in the WW movie (forgetting comic book canon) the Queen herself bids her farewell on the beach telling her that she can't come back if she leaves, and by every indication she has not in a century even if she was unhappy here. Ironically in the movie itself she "returns home" only when we see her dead! I know it's splitting hairs though, and I am swayed by the fact that in the other version this unnecessary contradiction was changed, for the better.
Correction: Flash not moving the others up the stairs could have been for their own safety. This ability has been shown to emit sparks and electricity. We're even shown earlier that simply running in trainers is enough to incinerate them and sliding across the ground is enough leave cracks on it. Moving people from one location to another could have resulted in them getting electrocuted or burned, so it was likely best to let them run up the stairs themselves to ensure each of their safeties as best as possible.
Casual Person
He rescues his future girlfriend and the ever important sausage without burning them and no bodily harm from the wrong amount of kinetic energy applied or anything, which could be another possible objection. It is honestly the weirdest 'heroic' sequence I have ever seen, since there are literally zero threats on that staircase. Maybe it's just intended as a full-on gag even if played straight.
Sammo
The two scenarios are very different. The scene where he saves Iris, he is merely taking Iris from her car, and placing her on the ground. With the hostages, he would have to take hold of them, and move them up several flights of stairs. The distance he would be travelling is much larger than the car crash scenario, and due to the increase in kinetic energy, this might put them at much larger risk of injury.
Casual Person
Another thing to note: You can see that when he grabs hold of Iris' body, he has to handle her body with the utmost care, implying that he has to be extremely careful when he interacts with others while using the super speed. And even in that situation, he is only placing her on the ground. So running back and forth moving the people up the stairs might not be the safest thing.
Casual Person
Not even from the car, from midair; he nullifies somehow the whole momentum she has and redirects it with no trauma (same as the sausage). Of course, not referring to the theatrical cut where he just carries people.But I'm not debating physics, just pointing out that (going by what it is shown, you can tell me he pushed into oblivion 8 parademons and 20 falling bricks off-screen) the hero just spends the whole time shouting "You ok?" at people, sparking lightning bolts everywhere.That's...something.
