The jokes were absolutely perfect:
Tony Stark: "I'm wearing a 3-piece Tom Ford, I'll get my other suit"
"FedEx Guy" - "Mr. Stank"
Captain America riding a VW
Bucky: "Can you move your seat up?"
Falcon: "No"
[Bucky moves over to the other side of the backseat]
Ant-Man: "I'm ready Arrow Guy!"
Spiderman: "Remember that really old movie, Empire Strikes Back?"
War Machine: "Where'd you find this guy?"
Iron Man: "He's like youngish, young guy"
Spiderman: "And they were like on that snow planet and they wrapped the legs of those walker things?"
Iron Man: "The kid may have a point"
The nod of approval by Falcon and Bucky after Cap and Sharon kissed:
Props to Sebastian Stan being able to turn off the WS and Bucky pretty convincingly.
I really like how they demonstrated Black Panther can still give WS and CA the work in and out of the suit if need be, we haven't had this strong of a Black live-action comic hero since Blade imho. The personalities of the heroes have really meshed well together into an organic chemistry (no Hydra) which made the split much more believable as it was built up since the Avengers.
In spite of all the characters thrown into the film, it felt natural and still and really about Cap's story which is he will not compromise in the face of overwhelming odds.
Definitely one of the stronger showings of the Marvel Franchise and will probably age fairly well.
Once Spiderman gets used to his powers
