The Martha scene is dumb as ****. Batman turns a 180 and goes from "I am going to kill Superman because if there is even a ONE PERCENT CHANCE that he is our enemy blah blah blah" to "OH MY GOD YOUR MOM AND MY MOM HAVE THE SAME FIRST NAME!! I AM GOING TO BE YOUR FIEND NOW!!!"
There is absolutely no logic to this whatsoever. It is contrived and lazy ********. Unconvincing ********. You mean to tell me that Batman wouldn't be smart enough to figure out that Superman was raised on earth by an earth woman? That that revelation would be so shocking to him that it would automatically change his hardened cynical worldview of Superman as fast as it does in Batman V. Superman? That is complete ********.
If ****ing Lois Lane could figure out that Superman was raised by an earth woman in Man of Steel I am pretty sure the Worlds Greatest Detective could figure it out. And why would it suddenly invalidate every concern Batman has about Superman? Why would it even matter?
You can't say this movie is "too smart for Marvel fanboys" when it has that kind of crap in it.
I agree with you here because Snyder is not a good film maker,
However... I think it has only a very small part to do with the two men's mother's having the same name... it's the name itself... here's how I saw the scene....
the entire reason a 12 year old Bruce Wayne transformed himself into Batman is because his mother and father were murdered in front of him. His whole existence stems from this fact.
Wayne studied to become a scientist, an inventor, a criminologist, and trained his body into the very peak of human physicality. All to avenge his mother's (and father's) death. The trauma for this man, everything he does is because of that moment. A man who dresses up like a Bat and beats up criminals at night is't exactly 100% sane.
Snyderverse Batman, after seeing the fall of Metropolis and the history of Robin being killed, etc etc. has made him snap, he's taking it out on Superman...
Does he really want to kill Superman?
He has lived his life to a code, that he seems to be breaking more and more every day... He's lost, he's forgotten why he's doing this anymore, he's no longer Bruce Wayne, he's now just Batman, engine of vengeance.
He has now self appointed himself savior of planet Earth ... but does he really want to kill? Does he really want to kill Superman???
He is on the brink of killing someone, he has made his decision, he has put his plan in motion, can he stop what is already in play??
But now that he is faced with actually driving the spear into this man's heart that lies underneath his boot, can he do it? Face to face, cold blooded?
Then he is suddenly reminded of his mother. It's not "oh you're Mother has the same name as mine" - what I saw was that the name of his mother, the last word that came form his dying Father's breathe, snapped him out of his black haze that he has been in. That blinded him to Alfred's advice...
He is suddenly reminded why he became Batman in the first place. That what he has been doing as Batman since the fall of Metropolis has been wrong...
He has an epiphany or hits rock bottom, or whatever it is, in that actual moment.
It's time to be Batman again, be the man that his parents would be proud of again.
That's how I saw the scene... but like I said, a better director could have pushed certain points... Snyder is Snyder...
