I enjoyed the intro. The whole spy thing worked in the beginning, prior to them all lining up, which works visually but didn't quite hit the spy motif.
I still don't know why Scarlet Witch has an American accent, other than just to make Elizabeth Olsen's acting better.
Lizzie and Scarlet duping Vision prior to Hawkeye betraying was nonsense. No one's side makes any sense, and the more complicated they made it the more obvious they really didn't want to go into the interesting stuff of what made someone evil, like Bucky, Zemo, Black Panther, etc..
Spider-Man was introduced well, but his portion of the story has nothing to do with the Civil War aspect. Nothing does. Then again, Stanley Kubrick introduced portions of film that weren't connected. Same with Steven Spielberg with Indiana Jones.
