It's a shame how lame Black Widow and the Leader were, because despite some of the movie's obvious b-level reshoot quality, I really vibed with the core of the film, between Ross, Sam, the tone, and the action. Like, I thought it kinda slapped.
As a lead, I think I like Sam more than Steve, who's kinda...goofy for my tastes, and I dug his story, just a worthy dude who just learned to believe in himself to fill the biggest shoes in the world, and I can't wait to see him leading the Avengers (hopefully in that majestic white costume again). Having Sam be a regular dude, almost takes the notion of Cap being the Avengers' leader despite being the weakest of the bunch to its logical conclusion, and thus having him go toe to toe with a Hulk was a perfect conflict for that, and more satisfying than watching Hulk vs Tony and his endless bag of tricks.
And the winged suit action is just endlessly awesome. Like when Sam and Joaquin take off together, it's like....yeah, this is way better than a Cap who doesn't fly. Speaking of Joaquin, while some have pointed out how he's lacking charisma, to me it feels refreshingly un-Hollywood. Him and Sam both -- no dramatic backstories, just the vibe of being regular people.
But yeah, with those huge flaws I don't think I'll ever subject myself to a rewatch. Or at least I'll have to keep a finger on the skip 10s button.
