Well. Superman didn't know where she was and this Superman isn't gonna take the risk.
I'll begin with this. So how can he find Lois in the amount of time it takes for her to fall from a roof? Halfway around the world? Trapped under rubble in the water? Either he can or can't do this shyt but when he goes from can to can't to can in the same few hour (his time) stretch it's too much to "believe".
My main thing is: the tone was soooo wrong. Bats and Super are sooo grimdark, morose, and downright mean. I own about 12 of the animated joints and from one creative team to the next you always get that "aww shyt Superman just showed up" and it feels like the "real" Superman even though different voice actors and animation styles. This dude looked like a version of Superman, but he never taps in to that Superman "It" quality. He was like a super powered do-boy. His orders never had weight.
Batman killing dudes to steal their stuff is just wrong. Batman. Killing dudes. To steal from them. THAT IS FUKCING JOKER/LEX/PENGUIN/BRAINIAC shyt. IT'S WHAT JOE CHILL DID TO HIS PARENTS. IT IS THE "REAL" BATMAN'S CORE MISSION IN LIFE TO ***STOP*** PEOPLE FROM DOING shyt LIKE THAT. So to me it just wasn't Batman.
I was sitting there not liking the movie. It has some cool fights but I never rooted for either one. Batman cause he was trying assassinate Super - and even in the comic Bats never tried to kill Super, just show him - and Super for just being an idiot and getting beat by a guy who is basically an insect to him. Like a tiny ass fruit fly.
It occured to me that this Batman and Superman might turn around and develop their morals because of all this grimdarkery. In the comics Bats and Super were straight up murdering for the first several years at least, then they developed into "boyscouts" that made me feel a bit better.. but.. me making up my own sequels in my head doesn't count for them making a good movie. I was sitting there bored and cringing at too much of it.
I give it three mics but two for the fights alone.
