DARK PHOENIX (2019) 9 p.m. on HBO. In an interview with The Times last year, the actress Sophie Turner discussed the moment when Simon Kinberg, the writer and director of “Dark Phoenix,” made clear how much the movie would rely on Turner’s performance. “I just [expletive] my pants right there and then,” Turner said. But she made it through. This most recent “X-Men” movie casts Turner, a star best known for “Game of Thrones,” as Jean Grey, a young mutant whose abnormally potent powers threaten to get the better of her. Michael Fassbender and James McAvoy reprise their roles as Magneto and Professor X, alongside Jessica Chastain as an alien modeled partly on Tilda Swinton. For the most part, Manohla Dargis wrote in her review for The Times, Kinberg “just moves characters from point A to B, pausing for face-to-face heart to hearts before the next blowout.” But, she added, “the mayhem is generally coherent and executed with clean, crisp special effects, even if Kinberg settles for slo-mo clichés.”
