Fun, action, humor, emotion, interesting, exciting...It checks all the boxes. You have to give props to Marvel/Disney for their casting choices. Absolutely no one is out of place (shame that hasn't transferred to Star Wars). One thing I've noticed more than ever going though the MCU films for the umpteenth time is Robert Downey Jr's acting. He really is just fantastic as Stark/Iron Man. I'd be perfectly happy if no one ever played the character again. This movie is what I expect a comic book film to be for the most part. I don't mind different takes on characters as that's the nature of comics but when I think about what I go into a comic book movie expecting, this film comes to mind.
