To show how behind I am on comics events, I just read Civil War. The plot concerns a superhero registration act that would require all superheroes to work for S.H.I.E.L.D. or become fugitives. Captain America is staunchly opposed to this, for some reason. Super heroes are all basically breaking the law anyway, so I'm not sure what the big deal is really. Spider-man for example, has always been an outlaw.
Iron Man is siding with the pro-registration forces. Iron Man's rationale makes a little more sense. Get all the capes organized under S.H.I.E.L.D. and get them trained and distributed across the country. When Stark offers to explain what he's doing to Cap, Cap fries his armor and sneak attacks him.
Rogers never really explains why this whole thing upsets him so much. Presumably, we're supposed to be drawing some kind of parallel to the Patriot act or something, but the whole thing bears no real resemblance to anything in real life. Somebody gets killed, because at least one person has to die in every event comic. *yawn*
Iron Man goes from seeming sort of reasonable to imprisioning people in the negative zone and letting supervillains out to hunt down Captain America's forces. I understand granting goofballs like the Trickster amnesty in order to make themselves useful, but Bullseye? Really? Bullseye is a mass murderer who I wouldn't trust to tie his own shoelaces without killing someone.
At the end Cap gives himself up to avoid more bloodshed. This is the same guy who refused to negotiate before, and was totally un-rattled by being pounded into the dirt by Iron Man or Goliath being killed. But, now he's just gonna give up. Apparently he really doesn't have iron clad principles or resolve. And that's the end. Cap gives up and nothing is resolved.
I feel like all the character's actions are interchangeable and nobody really elaborates on why they are one side or the other. We could just as easily have Cap leading the registration side against Iron Man and it would have made just as much sense. There are various other things that don't make sense. We see Cap, Daredevil and Luke Cage all get new secret identities...which they never use. For some reason, the Punisher seems to have a great deal of respect for Captain America. Again...why? Who cares?
Overall, Civil War comes off as a pointless mess.
