It was about her being heroic and inspiring which DCEU Superman has completely failed to be.
Well, I certainly can't argue with
that.
People complain that WW shouldn't beat up human enemies, when Captain American does that exact same thing in his movies with zero complaints. Cap was doing something very similar beating up terrorists to save hostages in The Winter Solider. No silly outrage when he sent people flying off ships with his kicks, but I guess it is ok because he is a... guy?
Har, har. No, we don't complain when Cap kills because he's 1) not a demigod or a hypocrite about killing, and 2) is an emotionally mature, intellectually keen adult. In
WW, Diana is emotionally immature (coercing a clearly PTSD-suffering combatant back into the field for no vital reason), as well as intellectually naive and alien to the modern world (she takes Steve's assertion that the Allies are the Good Guys at face value, and is completely ignorant of basic world history, such as the decimation of indigenous North Americans at the hand of European-descended whites). The use of child soldiers is internationally considered a war crime in large part because children under 18 are assumed to lack the emotional and intellectual maturity to comprehend combat, and the rationales by which societies wage war. By that standard, Diana is a child soldier.
Moreover, Diana fights German army
conscripts, many of whom were, by that part of the war, teenagers, whereas Steve fights not just Germans/Nazis but HYDRA Nazis specifically, who can reasonably be assumed to be especially vicious volunteers for said faction, and then terrorist mercenaries in the present day. Also, Steve reports to a military/SHIELD chain of command, whereas Diana does whatever the hell pops into her remarkably inexperienced mind. So no, their fighting isn't remotely the same, and it has nothing to do with gender. (Also, Steve repeatedly stresses he doesn't want to fight for fighting's sake, but rather to liberate Europe from the Nazis, whereas Diana's primary goal in life since childhood is to become a warrior. If she'd been a young
boy begging to learn the art of killing, I doubt it would have been seen as anywhere near as cute.)
Finally, Nazis - including everyday Germans conscripted under the swastika flag - earned themselves a specially villainous place in pop culture on account of an event called The Holocaust. But WW1 takes place decades before that... huh, wouldn't it be nice if Diana had decided to publicly reveal herself to the world after killing Ares? She may have talked Germans/Austrians/Nazis out of WW2 and The Holocaust to begin with. Needless to say, as a young American who only became super-strong after Pearl Harbor, Steve had no such opportunity.
Also those WW1 scenes were never about WW being in danger, but about her discovering her limits as a fighter.
What limits? No. Those scenes were about giving the audience cheer-worthy Wonder-Woman-kicks-ass porn. Which isn't inherently a bad thing! There was tons of female cheering in my theater during those scenes. But as cathartic and thrilling as it clearly was for many to see a super-woman kicking ass on the big screen with that kind of scale, we need not pretend those scenes had any kind of deeper meaning within the context of the movie itself.
