Just a lot of BvS Spoilers here...
Wonder Woman - I keep seeing how folks think she's the best part of the movie. My view? She was there. In MoS, We got Superman's origin - yet again. Here, we get Batman's origin - yet again. There's not a soul alive that is going to this movie and doesn't know the origins of these two iconic characters. And then, Wonder Woman is there.
Oh, Lex has a photo of her she wants to get back? Well, it's a good thing digital files can't be backed up or anything. Yeah, waste your time breaking in there to get it back. There's no way a mega corporation would have multiple dedicated backup servers of important files or such.
Oh, and Bruce has to go back to get his little dongle thingee? The guy has the technology to clone a cell phone by sitting it down next to another cell phone, but needs a physical connection to connect to these servers? Well, I guess you need a reason to get him back down there and to introduce Wonder Woman.
Instead of spending 20 mins telling us all Batman's origin all over again, why not spend that time giving us a montage of him beating the **** out of the Joker, Penguin, Riddler, etc.? Give us the sense that he's been doing this - and has been successful, for 20 years.
Oh, yeah, the media is freaking out because Batman is "branding" the bad guys... but all the bad guys he killed in this movie (not counting the dream sequences) - yeah... I'm reminded of the Badman/Penguin College Humor skit. They're just sleeping! By the way, if you've never watched them, go watch them. They're good. The Badman/Superman skit was 100x better than this movie.
Oh, those dream sequences? Those where totally out of place. I'd say they screwed the pacing of the movie, but that implies there was some kind of pacing to begin with.
So... Lex goes through the delicate process of cutting off Zod's fingerprints in order to gain access to his ship. That, apparently, he knows runs off Zod's fingerprints. Advanced alien technology and it does what our spy movies did in the 60s. Oh, and the very careful process of cutting off the fingertips? Why not just slice off his hand? Or, better yet, you're freaking taking his corpse to the ship with you... Just lay his hand up there.
Why are you taking his corpse with you anyway? Oh, the origin of Doomsday is "Lex smeared some of his blood on Zod's body, and Zod's ship uses that to bring him back as the iconic, unstoppable killing machine - now with heat vision, flight, and some kind of energy absorbing powers." Okay.
And Kryptonite. Guh. Okay, once you know Kryptonite is Superman's weakness, you're golden - but how do you find that out? The cartoon handled it well - the rock was on display at the museum, some bad guys tried to rob the place, Superman tried to stop them, got exposed to the Kryptonite, then Lex saw the footage and built a hypothesis and tested it out. Awesome.
In this movie... Lex finds some green, radioactive rock. Having tried everything else, I guess, he decides to see what happens to Zod's corpse when exposed to the rock. I mean, that's a logicial test to run "Hey, nothing else is happening. Let's try cutting him with pieces of dirt lying around."
Oh, Lex knows Clark and Bruce's secret identities. How? We'll never know. It's a thing that happens. Like most things in this movie.
I could rant more... but it just irks me. DC, I know you're like 6 years behind Marvel on building up and fleshing out your movie universe... and you don't have to copy them exactly... but seriously - they took time and nurtured the billion dollar movie franchise that we know and love. This... was terrible.
