Suspension of Disbelief: WONDER WOMAN

The story is set during the WWI. Apparently the Germans were Nazis then, who knew? Some of the German military helmets looked like WWII issue. Props dept. probably didn't have many WWI stahlhelms. Also, the heroes of the movie ask if something is "flammable." This dumbing-down of terminology hadn't occurred during the given time frame. They would have correctly used the word inflammable instead. And why didn't Chris Pine just dump the gas into the ocean? Duh!
