In other words, the character has been known for doing things on his own and tackling his problems with his personal resources and free will. Seeing him in the kind of setup that “Civil War” will introduce is going to be a bit strange for those who know him.
It’ll be even stranger to see him going around and forcing all superheroes to register with the government, according to those voices – this is the character who would gladly do as much as possible to remove government interference from his own work, and seeing him do that right now is quite strange indeed.
But in the end, there’s a lot that we don’t know about the upcoming “Civil War” that might surprise the franchise’s fans and make up for all the negative opinions that we’re hearing right now.
If the film is produced under high standards and depicts all characters in a believable way (that is, without taking a large detour from the personalities we know and love about them), it should still be an incredibly successful production and it will be remembered by Marvel fans for quite some time. And in addition, it only makes sense for the producers to want to cause some controversy in the community before the film is actually released, as that would be in their benefit in terms of generating hype.
