Including Spidey and Ant-Man changed the tone of the airport fight from what it could have been if they'd elected to keep BW's deleted scenes. Widow fighting with Cap and overlooking the destruction of the airport are a far cry from the levity/fan-service spectacle that Spider-Man/Ant-Man were included for. The Russos chose to make the airport scene "fun" until Rhodey got hurt. The tone/focus of the airport fight is one of my bigger criticisms about CW in general. The sheer number of characters is definitely something keeping me skeptical about IW.
