Captain America: Civil War was very good on the scale of summer blockbuster action movies, but pretty ordinary as far as Marvel movies go. That speaks both to the quality of Marvel’s output and a reasonable amount to be disappointed with in the movie. Spoilers to follow:
All the actors are well-cast. The old ones, obviously, but Black Panther and Spider-Man shine in limited time, too. It’s closer to Winter Soldier in tone, so it’s not non-stop jokey, but they do pepper in some humor throughout, and it works. There are some quality action scenes (though a little too much of the shaky-cam early on). My complaints lie with the whole hero vs hero conceit in general, and with the villain’s plan.
Captain America, believed to be the paragon of goodness, the conscience of the team, he thinks “we need to be able to ignore the borders of any country on earth and kick the shit out of people there without any oversight.” Which is a patently stupid position. If Captain Russia were swinging by Chicago to beat up some Hydra guys, we’d be rightfully pissed at the collateral damage. So naturally he gets half the Avengers to sign on to his stupid idea. Meanwhile, Tony Stark’s rationale for being for oversight is to look at the mess in Sokovia and be like “this is our fault.” No Tony, this is your fault for making Ultron. You’re taking the right position for a stupid reason. Maybe all those other Avengers sign on to Cap’s side because they’re like “fuck you Tony, at least take responsibility for your shit.”
Meanwhile, the main villain is Baron Zemo, reimagined here is as a Sokovian Col. rather than a Baron. But still Zemo. He has Joker-level ability to predict unpredictable events, because his plan relies on first creating a war within the Avengers, then them reconciling enough that two people will be at a specific place at a specific time so that he can have the big reveal that I thought was obvious from the beginning but hopefully some people were surprised by it. But it took a million things going right at exactly the right time for his master plan to come to fruition. Moreso than most contrived movie villain plots.
But it was an enjoyable time at the movies. Just an Iron Man 2/Thor 1/Cap 1 level enjoyable time, rather than being up there with the better Marvel movies.
