I had to watch it twice to make out whether I liked it or not. Saying that, even with the first viewing I still knew it was a good movie, probably one of the better Marvel movies at the time.
Spoilers will follow:
Again, I can't help but agree with Cap when it comes to why the Accords are a bad idea: People with agendas get to pick where the Avengers get to go. What would happen if the Avengers were denied deployment to New York, or Sarkovia? Sure, there were casualties, but that versus an extinction level event? Do they even want to play the math game there? We even saw that Ross had an agenda, and refused to even examine the evidence of Zemo manipulating the UN bombing: He had a public scapegoat in Bucky, and he wanted Bucky, damn the evidence.
The sad thing is, if Tony wasn't such a bag of dicks, Steve was willing to compromise. He was willing to sign the accords if he got to be part of the decision making process, if he got to put safeguards in place... and was seconds away from putting ink to paper before Tony casually slipped he was keeping Wanda in interment. The look on Steve's face said it all, it was like "God Tony, can you stop being a bag of dicks for just TWO seconds?" I like the fact that Steve has a fondness for Wanda, due mostly to the fact that he relates to her(as he said sarcastically to Maria Hill in Age of Ultron "What kind of person would allow themselves to be experimented on by a german doctor to protect their country?")
Also, in the end, the reveal that Bucky was the one that killed the Starks... I mean, I get the emotional reaction Tony had, but at the same time, Tony did know Bucky was mindfucked out of his mind by Hydra, and wasn't responsible for his own actions. Him going all Terminator... I mean, I get it, and I can even understand it.... doesnt' mean I have to like it.
Scott Lang and Spider-man stole the show during the Airport fight. Some of the best dialogue and fighting belonged to these two. Especially when Scott Lang whips out the Giant Man, his big trump card. I love how goofy and outright formal those two were acting during the fight. Also, this is one of the best Spiderman adaptations I've ever seen. THe costume, the personality... I even like this Aunt May. I was never worried about Marissa Tomei, she's one of the greatest actresses out there, but the idea of a hot Aunt May just seemed strange until I saw it.
