So this Superman won't save his dad because it will expose his powers.....but will go fight/kill Batman to save his mom?
The "nuke Superman" scene belonged in a G.I. Joe with how poorly it was done. 5 minutes after Doomsday appears, POTUS and the joint chiefs are ready to literally launch nukes at him? Sure.
Why does this incarnation of Lex Luthor hate Superman? Why does he know who Clark Kent is....in a world where Clark Kent doesn't know who Bruce Wayne is? And why is them meeting at his party a big deal to him?
The basics of this film would work a million times better if they would've taken their time and introduced this Batman in his own damn film. His arc in BvS would actually hold weight if we got the chance to see his descent. Would also have given the Lex/Superman relationship to breathe.
Man I'm tired of repeating the same things... But ok.
At that point in time, his dad in MOS didn't feel like the world was ready for people to see his powers. He was trying to protect his son. His dad expressed that throughout MOS... And this is before he was Superman. If he saved his dad, it would've been Clark Kent with superpowers saving his family. Not Superman ... Not hard to comprehend.
The POTUS already had Intel telling them there was no logical way to defeat Doomsday so it was a high risk, high reward way of beating the creature. In these movies, nuking creatures is the number one plan for defeating things not understandable threatening humans. Name a movie where humans didn't try to nuke threatening beings. Superman would be considered collateral damage...
How many times do we need to explain Lex's hatred of Superman... Especially since in every adaptation Lex has hated Superman
They didn't have time to introduce every character in their own movie which is why this was made. The universe already existed in this adaptation based off the clues in this movie and if any of the viewers followed the current universe as is. In MOS... Batman, Flash, Cyborg, WW, Aquaman, etc., already existed and were around but just weren't recognized until this movie... They did that on purpose. They were hidden, myths, or metas that were already being observed. The appearance of Superman brought them to the fore front. In which will be addressed in BvS and SS.
