You know, I wish all the Peggy scenes in the Captain America films were replaced with Howling Commando scenes, because then I would actually like them
Genuinely, think of how much more powerful CATFA's ending would've been if you could actually feel the loss of an ensemble of guys you've come to love, that Steve spent over a year with (and then Bucky of course, even if you just mean platonically.)
Like if the ending of The Fellowship of the Ring was Sam Gamgee dying protecting Frodo, and then everyone else but Frodo dies within one minute. And Frodo only got to say goodbye remotely?! Absolutely devastating!
And then Bucky'd come back in the sequel?! 😭😱 Imagine!
CATFA should've been visually inspired by Spielberg's war movies (ie. what it needs to be), instead of being a po-faced Indiana Jones or limp-wristed attempt at Casablanca.
And the most infuriating thing is you absolutely could cut Peggy out of the movies as-is and it wouldn't damage any storyline.
(Except that it was she who hired the Nazis & Red Room personnel that made Bucky into the WS; so you would just have to change that to, eg. Stark doing it instead. But that's all.)
Cutting her out of the movie would also create a space for Bucky to be in her place early on, which is much more accurate to the comics, and would give a deeper impression of Steve's prewar life; it's a much more elegant use of character.
Eg. Picture Bucky deliberately taking Steve to the Expo because, despite his fear, he supports Steve's desire to join the war, and he knows there's one last recruitment station there that Steve hasn't tried yet.
Being shocked to find Steve has successfully enlisted and now they're both being deployed to Camp Lehigh.
(Steve following Bucky to the train station and Bucky thinking they're going to have a tearful goodbye on the platform but instead Steve climbs aboard too. Maybe even sneaks aboard and when Bucky sees him he doesn't realise what it means and he's like 'Stevie you can't 'stowaway' into the Army.')
Bucky (obviously!) as the hard ass sergeant who's training Steve and the others through basic.
Maybe Gabe, Morita and Dum Dum among those training with them, to strengthen their emotional impact too (also to show Steve and Bucky's complimentary talents for command from early on, and how close the Howlies are with Bucky.)
An aside of Phillips complaining that non-white privates have been allowed into the potential-serum pool and bamf-jew Erskine being like 'we must consider there are more important qualities than race' or sth.
Steve throwing himself on a grenade because his oldest friend is standing nearby.
The guys growing to admire Steve so that when bully!Hodge gives him a hard time, it gradually becomes both Bucky and the other future-Howlies defending Steve.
Both Steve and Bucky successfully retrieving the flag, but in different ways to showcase their different mindsets.
(Future-sniper-with-murder-thighs Bucky can literally just climb that shit, whereas future-Cap!Steve does a Speech that inspires all the other guys to help him form a human pyramid so they can all get the flag Together. 😭
(Side-shot of Bucky watching him, smiling in warm admiration and you have an 'oh... that's what he sees in him' realisation.)
Asides of Dum-dum and Morita just trying to fight everyone for the flag, devolving (of course) into fighting each other, while Gabe's just standing off to the side pinching the bridge of his nose going 'guys... guys... the pole can be taken down... fellas...')
Bucky being offered the superserum first and telling Erskine to give it to Steve instead.
(Erskine exchanging smug eye-contact with Phillips, because neither of them were Phillips' first choice, but Bucky has just vindicated Erskine's certainty that Steve should be the one, and that Bucky is great also. Like maybe Steve is going to be patient zero but Bucky will patient 2, if Steve's serum is a success -- which doesn't happen after Erskine is killed. Or so they think.)
Aside about good-candidate Gabe being passed over for serum as a nod to the mores of the time, instead of acting like racism just doesn't exist. (Maybe there's also a scrappy black kid called 'Bradley' whom no one takes seriously?)
Bucky being there with Steve in their hometown (!) when Steve takes the serum, attacking him in a hug when he comes out of the vitaray in one piece, bursting into tears because for the first time in their lives Steve isn't in any pain.
Bucky being the one on the street who shoots a car driving right at him and then gets tackled out of the way by Steve, so that it can become a cool foreshadowing call back in CATWS when 'the WS' shoots Fury's car and then coolly pivots aside, just like Bucky planned to do in WWII!! (And also the second time Steve almost saves Bucky from certain death, only it's as beefy!Steve this time and Bucky is gobsmacked?)
Cut from Steve's newspaper front page to Steve and Bucky at Bucky's family's for one last home dinner, and all Bucky's sisters just sitting there mute with their jaws dropped, staring at their annoying little adopted-kid-brother Stevie looking like an absolute beefcake. (Maybe Bucky's Mom staring too and Bucky being like 'Mamina!' 😫)
And then Steve's devastation because he assumed he'd be deployed along with Bucky and the boys, but instead he's shunted off into the USO tour.
Steve coming to rescue Bucky and the guys in the cells recognise him and cheer and are delighted by his costume.
Bucky knowing already that he has serum, like he should've done in CATFA anyway (because Steve was front-page news and of frickin course he would've been writing to Bucky the whole time?)
Steve and Bucky discussing how they're going to stop Phillips vetoing their choice in team-mates, given segregation and all, and savvy-Bucky being like 'I might have an idea about that.'
(Smashcut to Phillips yelling at Steve and slamming down a newspaper with a front page photo of Steve and the Howlies -- because Steve already leaked to the press and now the Army can't stop him.)
And that's just off the top of my head!
So you can see how neatly and organically it would all fit together, using Steve's arc in a way which coincidentally also gives you time to fall in love with Bucky &Co. so that their 'deaths' hit you as hard as they hit Steve.
Golden artistic adaption opportunities wasted just because of stupid amatonormativity! 😪
