NobodyVery few people liked the Civil War comic plotline. That's a large part of why they are using it In Name Only for the most part, the central issue of this 'civil war' is entirely different.
I actually liked the concept of Civil War (the comic book). I just think that it was doomed. You needed established characters, but you couldn't leave the universe status quo as per usual. It would have caused some permanent shifts that I'm not sure the Marvel Universe could absorb (case in point the magic retcon that happened to Spidy despite Joe Q. Saying no). I mean some stuff changed, but it wasn't nearly drastic enough.
The idea of Super Hero Registry is not a terrible idea, but it would be kind of something you'd end a universe on, so you know it could never happen in a big Universe like DC or Marvel.
Continuity Gordian Knots, whatcha gonna do.
Though I'm happy that the movie is only taking the name. It'll probably have more to do with Hydra. (Trying to keep myself as blind as possible before I go see it.)
