In “Mission: Impossible – Rogue Nation,” Tom Cruise runs faster, fights harder and flies higher. At 53, the actor seems more intent than ever on cementing his beleaguered star power, and he invests so much into his fifth outing as the tireless super-spy Ethan Hunt that he wins you over. For much of the film’s two hours, you forget about the real-world Cruise and all the problematic baggage he carries and just marvel at his efforts, even if they bear a whiff of desperation.
