To the bolded: Agreed, agreed, agreed!
I love that they absolutely nailed the core of who Steve is, at his core. They perfectly distilled his essense.
Winter Soldier, while a fantastic movie, was a very poor representation of the actual 'Winter Soldier' story. That's okay though, because the story was complex and layered. It was drawing on plot threads that would be impossible to develop onscreen. Thus, my (admittedly stubborn) insistence that the films - no matter how good - are inferior to thier source material.
The idea that SHIELD is corrupted is, in itself, not a new story either. Secret Warriors is actually the
third such story (and the second featuring Hydra). SHIELD in the comics has been rebuild from the ground up several times.
It was handled brilliantly in the film (and managed to avoid Nick Fury in bondage gear, ala 'Nick Fury vs SHIELD').
It sucks that you're not enjoying the current direction of Captain America in the comics. I've been enduring the same enui during Wonder Woman's current run, and it's no fun.
There are reams of Captain America comics out there to enjoy though. I've no doubt that there's a story waiting for you to uncover that will blow your mind. Brubaker and Gruenwald combined runs are still just a mere fraction of the material out there!
