The reveal of "IT WAS HYDRA ALL ALONG" really, really bugs me, too. One of the reasons Cap is my favorite superhero - particularly the way Evans plays him - is that he represents the best of America as an idea, including questioning authority or problems within American history/the American experiment. So it just feels wrong during the Toby Jones scene (a very cool scene aesthetically) to basically put the blame on America's foreign and domestic policy misadventures of the post-war, post-Cap era on a band of super-secret super-smart super villains. It feels like a betrayal of the character, because what makes Cap Cap is his ability to recognize America's mistakes. More than that, it feels like (pretention ahoy) a cultural absolution for American fuck-ups of the last fifty years. Vietnam? Hydra did it. Iranian coup? Hydra did it. Destabilizing Latin America? Hydra did it! Spying on MLK? Hydra! Which makes it even more annoying that they kept using "conspiracy thriller" comparisons, because those movies were in direct response to America not being the good guys anymore, specifically through the lens of Vietnam.
I hear what you're saying about not expecting much out of these movies, though. I think that's eventually where I've wound up - I know not to go in expecting much, but just a good time, well-made. That's why I said I enjoyed Civil War and Doctor Strange more once I had some time between release and watching them/watching them again. I'm looking forward to Thor 3 and Guardians though.
