“X-Men: Dark Phoenix” (*** out of four) was a pensive final entry in the “X-Men” series focusing on Jean Grey (Sophie Turner) who suffers a tragic accident as a child which leads to her gradually developing superpowers that turn into the Dark Phoenix who threatens worldwide destruction while the rest of the X-Men (James McAvoy, Jennifer Lawrence, Michael Fassbender, and others) have to decide whether to save her or save the universe. Twelfth entry in the “X-Men” franchise (and a direct sequel to “X-Men Apocalypse”) is a satisfying conclusion to the series, with the expected array of dazzling effects and action sequences. Turner’s strong performance and melancholy aura and Hans Zimmer’s terrific music score are a good help for some occasional lulls in script.
