I've only seen Endgame twice.
The second time was I able to - not set aside the things I dislike, completely - but just take in the movie in its entirety and catch everything. I enjoyed it more the second time, even though the major things I disliked - Thor/lack of Loki, Falcon Cap and the general waste of Bucky and Steve/Bucky's relationship (central to ALL 3 of Cap's films), and the writing/handling of Hulk/lack of payoff for Hulk, are still there and aren't going anywhere. My mind wasn't changed on any of that, though I suppose a potential Thor 4 might mitigate some of my issues with the lack of a good "culmination arc" for Thor.
Setting aside those things, I genuinely enjoy much of the rest of the movie. We're plan on seeing it a 3rd time this weekend, and that will be it for me.
I like the idea of Cap being worthy in AOU. I never much cared for some of the spec I've seen that he was only worthy post CW cause of Tony's parents and Bucky.
