The thing is this ties into Bucky Barnes, but Civil War is - or should be - about more than one man. See, the original Civl War - comic book, not real thing - was about how far we go to protect people and how much heroes have a right to a private life.
Not that I liked the Civil War crossover all that much. I tried rereading some recently and still did not like it all that much. That being said, it was trying to be big and show how contentious ideas and fracturing of the heroes due to different ideals could end up. It was big and serious. It was big. As much as I love so many Marvel characters, it was bigger than everyone one of them. It was bigger than my love for each separate character put together. And I applauded it for being about that, for trying even if it didn't really interest me.
Which is why a comic like this that focuses solely on Bucky and Cap's search for his old friend worries me. It's why, as awesome as the previews look, the cinematic Civil War worries me. I get what they're trying to do it, and how they're trying to personalize it, and make the struggle more relatable. I just think it might be a big mistake. (They couldn't do this, at least not with Bucky, in the comic book version, but Bucky has more history. And I think it's smart that if they have to do it, they do it for Cap and Bucky.)
That being said, this was an enjoyable story if I could manage to forget why this is a bad idea. I was reminded just enough, and then again at the end where they say this is going to be continued in the movie, that I couldn't quite enjoy it as much as I'd wanted to when I purchased this. (I bought some Infinite comics because I remembered how much I liked them.)
It was a valiant try, Marvel, I will give you that. If it weren't leading up to Civil War, I suspect this would have been a four or four and a half star read. I salute the effort, but you've still got me worried about this movie, maybe more so than before. (Especially since the original event was all about spectacle and all the heroes choosing a side. Your sadly small cast in comparison? Does not bode well for the movie either. I do hope I love your movie, but I've yet to see anything to convince me that I will.)
