Some people really do have seriously questionable taste. What must your media consumption and influences be like to cause you to prefer such a mess over a great movie?
Endgame was made by people who know how to tell stories that are satisfying and entertaining. It manages the daunting task of concluding a massive story, full of moving parts inherited from 20+ prior films, with events that ring true for characters we know well, while striking a fitting balance between drama and humor. The movie is coherent and well paced, with spectacle that only ever arises from the needs and conflicts of characters who behave as though they have rational motivations.
It's fucking nutso to dismiss the high level craft on display there by comparing Endgame unfavorably to a half baked mess like Dark Phoenix, which so obviously lacks the spark and organization of good character-driven storytelling.
