Civil War is an abomination and everything about it is dumb as trout.

This is how dumb it is: The Pro-Registration side employs Green Goblin, Venom, and others. To perform officially sanctioned government work. Not in some sort of vaguely clever "We need bad guys to stop someone even worse" way, they just... hire them.

Meanwhile, they throw dedicated and proven superheroes who have an objection to either the principle or implementation of registration into the Negative Zone with no due process, no lawyers, no trial, no appeals, nothing.

But more than anything else, there was a total failure of communication between all the different writers. Everyone had their own ideas about what the arguments were and who was in the right, which could have been effective if it had been done well, but it happened due to sheer incompetence on the part of Joe Quesada.

Oh speaking of him, remember when he explicitly said Spidey's revealing his identity would not be undone through some "magic retcon" (exact words) and then in One More Day (Which is atrocious for plenty of other reasons), literal magic was used to undo the revelation and make everyone forget? Yeah that happened.

Plus of course one of the main viewpoint characters who we are supposed to feel has her head screwed on right, delivers to Cap what is portrayed as a huge verbal smackdown that shows him just how out-of-touch with Modern America he is. Because he doesn't watch NASCAR, use MySpace, or vote on American Idol. Has swears, but this is how that vapid idiot should have been treated.

And the details of the Registration Act varied according to different writers, because there was apparently no brief or anything.

And SHIELD tried to arrest Cap before the law was even signed into law. Putting aside that generally a law doesn't get enforced with SWAT teams and stuff at 12:01 AM the day it comes into force, especially if it involves registration, because you give people time to comply with it. It can be done, but it's widely considered bad form and a lot of court cases would be launched because how can you register when you get arrested before the registration centers open? Oh but nevermind because, of course, the law simply doesn't apply here.

Oh and remember when Stark had Black Panther's wife attacked for refusing to sign, even though she, as wife of a foreign chief of state, would almost certainly have diplomatic immunity, to say nothing of the fact that pissing off Wakanda would be almost as dumb as pissing off Atlantis in the DC-verse.
