*****SPOILER ALERT for what is supposed to be a major spoiler for Wonder Woman, although it seemed pretty obvious. Also a bit spoilery for T2 but given that you are reading this that probably isn’t an issue at this point ****
One of the things that struck me about James Cameron’s tone-deaf rants about Wonder Woman, was that in the first one he said of Sarah Connor “…,she was a terrible mother, ….” This seems a bit odd as it certainly has nothing to do with comparing her to Diana who is not a mother. It does bring home the fact that James Cameron for all his claims of being 
“feminist” does seem to be a bit fixated on women as mothers. Especially as “terrible mothers.” Remember, he turned Ripley into a “Terrible Mother” who is guilt ridden over missing her daughter’s life and finds redemption in taking care of an orphan. This is just another problematic issue.
First, I don’t really think that Sarah is a Terrible Mother, as such, but rather she’s a mother faced with a overwhelming task to raise a child she knows must face absolute hell and who she also knows she must prepare him for it. This certainly turns her into a dysfunctional mother in many ways, she was not a warm and cuddly mother, at least by the time we see them in Terminator 2. Sarah is not gentle with John, she speaks harshly to him, a harshness she knows is nothing compared to what is waiting for him She may well have never baked one fucking cookie out in the jungle. She might have at one time. She may have once tucked him into bed with a story, but she undoubtedly included stories of how he was the Savior of Mankind, rather than to convince him otherwise. She loves her child, but she knows the truth, she’s the only one who does, and it refocuses the way she raises her child.
Before T2 happens, Sarah decided she could not have her son face such a horror, nor could she let humanity face it if it could be stopped. She set out to try to stop Judgment Day before it happens. “She tried to blow up a computer factory but she got shot and arrested.” This, of course, means John ends up with another terrible mother as well as terrible father in his foster parents. It cuts Sarah off from John when she knows he is now being told that all she taught him was a lie and that he is even more vulnerable. She wanted to stop what was going to happen to him, but failing that needs to make sure he can still grow up to be the Savior of Mankind.
When they are reunited it is with Sarah’s greatest fear not only happening but walking right into the asylum. Primal terror kicks in to her already high adrenaline drive and she doesn’t seem to register that her son, who she is so desperate to get to and protect, is walking right in with her nightmare and her first response is to flee. It’s only her son who can bring her back to the present and allow her to adjust to the actual information that this nightmare is there to save them and a greater nightmare is now after them. She never responds lovingly to her reunion with her son, his moment of hope that she might is actually a check for 
injuries followed by scolding him for risking his life for hers. It’s her job, after all, to risk hers for him. She’s on overdrive, she’s still in primal instincts which now have returned to being about protecting her child and assuring he is so far okay. It seems cold, but, honestly, it’s also understandable to me. Apparently, not to James Cameron.
Of course, Sarah returns to the decision to stop John’s (and the rest of the world, all the other children) hellish future. She doesn’t make the greatest choice for that, but she moves forward immediately, leaving her son with a guardian she believes can protect him better than she could. She likely saw herself even more expendable now that a machine can guard him.
Everything Sarah does is to protect her child but also protect the world. He must be protected and prepared to save mankind if she fails, but she will do everything she can to try to keep him from every having to face doing that. She might not be a typical mother, but I don’t see that as terrible.
Hippolyta was charged with exactly the same task, raising a child, Diana, who is the Savior of Mankind. Rather than a time traveler sent back by her child the messenger and father is the God Zeus. Like John, Diana is meant to be trained and prepared for the task ahead and if she fails it could be the doom of humanity. Hippolyta deals with this mission rather differently than Sarah.
Hippolyta lies.
Hippolyta might not bake cookies either, but I’m sure she has a servant who does. Despite being queen, she does seem to be a warm loving Mommy who cuddles Diana and tucks her 
in at night with bedtime stories. Bedtime stories are designed to gaslight this Savior of Mankind into believing she anything but. To lie to her about what the God Killer is. To try to convince her not to want to train to prepare for a battle she doesn’t even know she is supposed to face. Hippolyta tells Diana the story of the Amazons, of the war between the Gods, of Ares’ vanquishing but also that she, Diana, is made of clay with no father. And she speaks of the God Killer as if it were a thing, a sword wielded by the mightiest among them, “and that is not you, Diana.” She is gentle and is dooming her child and all of humanity through her gentleness.
Hippolyta lies. I am far from the only one who has noted that Hippolyta is one of the villains in the movie.
Unlike Sarah, despite not wanting her child to face what she must, Hippolyta never chooses to try prevent it by facing Ares herself. Unlike Sarah, Hippolyta refuses to train her child for 
what is to come. But fortunately, also, unlike Sarah she is not alone in knowing that Diana is the Savior of Mankind. All the other Amazons know it, but even her sister cannot turn her around, choosing to add to lies by training Diana in secret.
Even after Hippolyta catches them training and is then convinced to allow it, even while she does tell Antiope to train her to be better than even herself, she still does not reveal the truth to Diana. At every turn she claims that the more Diana’s ready to face Ares, the sooner Ares will find her. Even though the less Diana is ready, the more likely she is is to fail. She continues this even as Diana is leaving to seek out Ares not knowing she is the God killer or the real extent of her power.
Both these mothers have a horrible burden to raise a child who is meant to face horrors to save the world. Neither wishes this on their child, but it is their fate as well as humanity’s. Yet while Sarah does everything she can to make sure John is able to fulfill his destiny, then tries to prevent it by putting herself on the line to try to stop Judgment day; Hippolyta does everything she can to prevent Diana from fulfilling hers, yet never tries to take on the burden herself. Sorry, James Cameron, Sarah has nothing on Hippolyta when it comes to being a Terrible Mother.
Sarah was also a “real person.” You know, as far as action film characters go. Like, say Kyle Reese. Wonder Woman/Diana is a comic book super-powered superhero, like Superman. Not even like Batman whose only super-power is that he’s rich and dysfunctional. In fact, while Superman is an alien, Diana is a fucking Goddess. Okay, the Goddess part is a recent addition to the character in the comics, but even before she was revealed as a Goddess she had been bestowed with “the strength of Hercules, the wisdom of Athena, the speed of Hermes and the beauty of Aphrodite.” So being 
beautiful is a canonical part of the character, although how she was drawn did change with the ideals of beauty at the time. And as either supernatural Amazon or Goddess, if she wants to come out of a battle with perfect silky hair, she can and always did.
