Despite the ups and downs the X-men movies have had during their 19 year run, "Dark Phoenix" still feels particularly disappointing. Most of the action sequences are rather underwhelming, the antagonists are as underdeveloped and uninteresting as they get and fan favorite characters are either completely missing or spend the entire movie being confused about what their motivations are. Easily the movie's biggest problem is its pacing, which is so fast that it leaves very little time for any kind of development that could have gotten the audience invested in the story and characters.
