I don't know how it "made sense" that Crossbones was working for Zemo. Zemo showed disdain for HYDRA when he tortured one of their soldiers, and had no problems killing him (he even says that "HYDRA deserves its place on the ash heap. So your death would not bother me"). Not to mention, the entire event in Nigeria was about Crossbones creating a diversion, stealing a biological weapon in order to draw out Steve Rogers and ultimately kill him as revenge for what happened in Winter Soldier. Zemo and Crossbones had nothing to do with each other and had completely different goals in mind for what they wanted to accomplish (killing Steve vs. destroying the Avengers from within).
Furthermore, how is the mess at Nigeria lucky? The Avengers being unable to contain the explosion is a culmination of what the Sokovia Accords were all about: The Avengers inability to minimize as much collateral damage as possible and disregarding borders to different countries. There was the Battle of Sokovia, Battle of New York, the Helicarrier Crash in D.C., and so on, which is enough of a sample size to show that the Avengers had an issue with collateral damage, which in turn, created the basis for the Sokovia Accords.
That's not what I said. I said Cap didn't want accountability
without failsafes in place to ensure that he's able to do his job, and that another HYDRA-S.H.I.E.L.D. event wouldn't happen again. Multiple times throughout the film he's referenced that working under the Accords could limit his job, be forced to work under someone's agenda rather than for the greater good.
Actually he
did try to work within it during his conversation with Tony. He refused to once he heard that Tony Stark was basically keeping Wanda Maximoff under internment, which confirmed that Tony is operating under guilt and self-preservation rather than doing what's right (though that's not to say that Rogers didn't have his own flaws either which is what made the conflict compelling).
Classic Bleepey (counter)argument where you assume it's an understanding problem when it has nothing to do with that at all.
Clark's own presence tipped the scales before Luthor could do anything, especially during Man of Steel as people (both close to Clark and throughout the world upon Zod's arrival) were mixed in coming to terms with an alien that held more power than anyone could ever dream of. There was also the end scene in Man of Steel where Swanwick was skeptical of Superman's motivations considering he knew he could break borders at any time. And yet, Superman left it up to him to convince Washington that he will operate not only under America's interests, but also for global interests. So when it comes to BvS Luthor actually didn't add anything, especially when the situation was already volatile. As for the bullets, that still doesn't make any semblance of sense to blame Superman for that when he doesn't even brandish a weapon.
No, this is what you're doing:
Trying hard to force similarities between the two films when both have different ideas for the hero vs. hero conflict story. Even the way you force similarities in characters make no sense. Superman is getting blamed for different reasons that Bucky is, Black Panther has his own motivations for going after Bucky vs. Batman who perceives to do things for the greater good of mankind. Also are you admitting that Batman didn't investigate as thoroughly as he should have? (which is lolworthy considering how much you have defended Batman's inability to investigate).
As for Luthor, if he was really manipulating things, then why did it take him to literally force Superman to fight Batman to get anything done?
Even Luthor's own plans doesn't even fit the definition of manipulation. I didn't say Zemo is a master manipulator, but at least he knew how to play both sides into doing what he wanted, unlike Luthor who wasted time and effort doing redundant things that didn't influence anyone until Superman was forced to fight.
