If you were to put 2016’s blockbusters in a museum, Batman V Superman: Dawn of Justice and Captain America: Civil War ought to be displayed next to each other. They’re the sort of movies that, when looked at together, take on a whole new dimension. Because one is far more successful than the other.
To understand why Civil War succeeds, you don’t have to look much better than at how BvS fails. Both movies have the same conceit: Two heroes fight each other. Thus, if you want both characters to remain sympathetic, they’d better have a dang good reason to be fighting. Funnily, both movies end up on the topic of collateral damage. In Civil War, Tony Stark/Iron Man and Steve Rogers/Captain America disagree on whether to put the Avengers under UN oversight, something that is complicated when brainwashed assassin Bucky Barnes enters the fray, forcing Steve to go outside the law. Bam, conflict.
In BvS, Batman doesn’t like how Superman is so powerful and causes so much collateral damage, and Superman doesn’t like Batman because he, um, takes the law into his own hands? Right off the bat the difference is clear, Civil War had a clear conflict, BvS was murky at best. Watching BvS, I was never sure why they were fighting, what it was they disagreed on. Furthermore, BvS has no complications in the conflict between Batman and Superman; they don’t like each other in the beginning, and continue to dislike each other the same amount until the fight. In Civil War the accords form the initial conflict, which then get complicated by Bucky’s reappearance and what they uncover about Zemo. Meanwhile, in BvS, the status quo between Batman and Superman doesn’t really change.
Which is weird; you’d think that with Lex Luthor running around with Kryponite and Zod’s corpse he’d be in a good place to incite some tension between the two. However, he doesn’t have any direct bearing on the plot until he kidnaps and threatens Superman’s mom well into the second hour (blowing up the Capitol sends Superman into exile and doesn’t directly escalate the conflict between the two heroes). Compare this to Civil War, where Zemo (who fulfills the same role as Luthor) blows up the UN (and frames Bucky), thereby setting Cap on a path that’ll put him at total odds against Tony. That’s before he sets Bucky on the other Avengers too, by the way. In other words, Civil War escalates the animosity between its two heroes. By the time they come to blows, we totally get why.
The coming to blows bit is where we see another divide. In BvS, Batman and Superman’s fight is just a skirmish before their big brawl against Doomsday. Civil War has a big airport fight with all the heroes happen before Steve and Tony’s one-on-one. This ordering shows where the priorities of each movie lie. See, you save the best, biggest, and most important climax for last. Rey and Kylo fight after Poe blows up Starkiller base. Frodo climbs Mount Doom after the battle of the Pelennor Fields. If the fight against Doomsday is the Biggest Moment of BvS, then the “Dawn of Justice” subtitle becomes the most important part. Which is weird, because the whole movie up to that point has been ploddingly trying to excite us to watch the heroes fight, only for the big thing to be them teaming up. Despite Batman versus Superman being the dang title, the ending tells us we’re not supposed to be interested in watching them fight. In Civil War, however, Steve and Tony throw down comes at the very end and proves a catharsis for the entire movie.
Okay, so, there’s actually a lot more about these movies. Both of them have a third party who joins them in the climax, though where Wonder Woman gives interesting looks throughout, Black Panther brings an additional point of view to the plot and ends up being the only true hero. Both have heroes manipulated into fighting, but while Lex kidnaps Superman’s mom, Tony finds out Steve’s best friend kill his parents (and so Tony fights Bucky [and Steve] because he wants to, while Superman is doing it because he has to). Then there’s also BvS contorting Batman and Superman into being funhouse mirrors of their accepted selves to fit the plot, while Civil War sees Steve and Tony’s own flaws orchestrate their undoing.
But I’m at my word limit and it’s getting late here, so I’m ending this here. Point of all this? Sometimes it’s worth watching a lesser movie to appreciate one that does the same thing better.
Except for Fant4stic. That movie just tells you what not to do.
