It's been a while since I've seen some genuinely awful hot takes.
The First Avenger is a fantastic film and firmly establishes Steve's character, cementing him as the heart of the MCU. To write it off as nothing more than military propaganda just seems so incredibly cynical and, frankly, ignorant, if not edgy for the sake of it. Captain America was literally created by two Jewish men who were fed up with Hitler and the Nazis and created a character who symbolized American ideals. The cover of the first issue had him decking Hitler in the face which, at the time, was an incredibly controversial political statement, as the US hadn't yet gotten involved in World War II. By definition, yeah, it's technically propaganda. But are you really going to discard something because it's anti-Nazi propaganda? If so, yikes.
It's a story of a man who wants to help, who wants to do what he can to fight back against some of the most vile creatures ever to stain the pages of history, because to him, it's the right thing to do. And he's chosen for the Super Soldier program not because of his brawn, but because of his heart. When he jumps onto the dud grenade at the camp thinking it was live, when everyone else tried to run from it, it established Steve as a hero. And the film doesn't shy away from recognizing wartime propaganda either, with the war bonds and such, so I really don't see what your problem is.
Nor do I think the ending is bad. It's anything but. Steve saves countless lives at what he believes is the cost of his own, only to be in stasis for seventy years and end up revived in the 2010s. He becomes disconnected with the entire world in a way no one can imagine. It's a tragically bittersweet ending. He saved countless lives, his own life was saved, but he became a man out of time.
To write off Civil War because you didn't like Zemo/the Bucky twist is one thing. I think it's a dumb take and I definitely don't agree with it, but I can live with it. But what I can't take is an opinion born from ignorance. To pejoratively write off the literal origin story of Captain America as military propaganda just shows me you couldn't look past your innately biased view of "anything being remotely positive about the US military is the bad." It shows me that you ignored the out-of-universe context which facilitated the character's creation, ignored the struggles of Jack Kirby and Joe Simon, who brought him to life. The movie is literally historical fiction. It's basically a period piece. I'm sorry if World War II existing is too far into the realm of "military propaganda," but it's literally integral to the character. For someone to get their knickers in a twist over a character who is literally a soldier having to fight in a war, I think they're just looking too hard for something to complain about.
So yeah that's my rant lol.
