After the whole arc of Ant man in his own movie to make it straight so he can be a father again, it's all throw away by the window and he set right back to jail
Spiderman really felt like a last minute addition, it's really the first time in an MCU I feel like a character introduction is just there to introduce the character, in the end, he has almost no impact on the story.
But the worst part is that I was hoping they wouldn't go with the "I have a really good reason to go of the gridd, if you listen to me-LALALALALALA not listening I am too mad at you, plus if I actually try to listen to you, the writers won't be able to find a good reason for us to have a cool fight", yet they walked right into it.
I know it's not a popular opinion, but I really liked Age of Ultron. It's really weird to see so much hate that movie while Civil War is being praised.
