Coming out of the film this afternoon this was something my housemate and I were discussing a lot. You know, so much of me really wishes they would dare to go there with Steve and Bucky, although I understand why they never will - put Bucky's backstory in a female character's body and there would be a 1000% chance that would be Full Romo, and I'd even go so far to say you'd get a romance unparalleled in the MCU* (sorry Tony and Pepper, I can't care enough for your will-they-won't-they). Steve risks EVERYTHING for Bucky, time and time again, to an outlandish degree: there were times in this movie where even I sat there in the theatre like 'Steve man, get a grip, you need to let the guy go!' Not to mention that here it really becomes clear to Steve that Bucky is really the only link left he has to his old life, that he means more to him that his new Avengers family even when he's a brainwashed psycho-assassin... Despite all this, though, you can't deny that the tension between them from Captain America: Winter Soldier definitively dissipated into a firmly Dude Bro Thing, which makes me wonder if that wasn't a conscious choice on the writer's part. Ah well. I don't watch mainstream media for its canonical m/m content; I know better than that.
*(Doesn't help of course that Agent Carter 2.0 is so vapid and not a patch on Peggy. Yay for shoehorned romances...)
Anyway, slash rants aside, I really enjoyed the film - standouts were Spiderman's spunky debut and anytime Sam and Bucky were in a scene together. Genuinely cracked up a few times, and although the beginning was a bit slow I think it was well worth the pre-release plaudits. On to Infinity War!
