This is also, objectively wrong.
The scene: 1. shows WW's abilities; the clapping of her bracers together, flight, fast, strong, etc. 2. She defends innocents and fights defensively 3. She is specifically a feminist hero 4. Justice is a motivating
ideological factor in her heroism. None of this exists in the film prior to WW showing up for this scene- this is the first presentation of her abilities and actions in the film.
Now, I'll go along with you for the sake of argument. Let's say every single person who saw this film knows all those things about WW before the film even starts.
Even if that were true- which it isn't, my mother has no clue about anything Wonder Woman related (ex); as presented the scene absolutely accomplishes what the filmmaker set out for Wonder Woman. The filmmakers wanted to show WW as fast, strong, defensive, able to clang her bracers together & knock people down, has a rope, etc.
