OK I definitely bought into this. I felt it came across genuinely and heartfelt, earnest, much like Peter Parker himself. Starting off with him working alongside Tony Stark, and having him pulled along not quite unwillingly, but definitely without the full story of what's going on. Tony comes across the worst here, as someone who looks down on Peter, treats him like a child, and pretty much tells him what he should think and do if he wants to be just like Iron Man...I didn't care for the part where Peter says he's been just like a father...
Eventually, as things heat up, Peter is forced (or as close to forced as can be done without a gun to his head) to reveal the one thing he's kept secret as long as he could...
After that, Tony condescendingly manipulates him even further, and leads him and other Pro-Registration forces into battle against Cap and his Anti-Registration rebels. This leads to a fight between the two, and even as enemies, the respect and admiration for Cap shines through.
Eventually, Peter comes to realize that maybe what Tony (and Reed Richards, Hank Pym and others) is up to is not quite what Peter had in mind when he signed up...he's forced to make a decision about where he stands.
In the aftermath, things change and he finds himself completely unsure of himself, other than the support of MJ and Aunt May. The words of one figure tell him what he needed to know, even though he'd already decided for himself. Inserting the words of Mark Twain on the subject of country is a great idea, and really lends gravitas to what's going on.
The end of the book makes us think things are going to work out for Spidey, one way or the other, when the unthinkable happens as a result of a major choice Peter makes in the opening pages.
This was one of the best Civil War books I've read, along with the actual Civil War itself. Spidey is so involved in the storyline, getting pulled on both sides, I feel this is the most accurate portrayal of what the honest Peter Parker would actually feel.
Well done all around, though I didn't care for the art jumping around as much as it did, it's still terrific.
I really enjoyed this, because *SPOILER ALERT*
having someone major from the Marvel Universe change his mind on which side he was on is perfect, especially because he doesn't do it for silly reasons; he agonizes over the decision, before he feels he can live with what he's chosen. So much happens here, Spidey will never be the same.
