Terminator Salvation restores some of the balance of huge explosions and emotionally compelling plot to the Terminator series. Set entirely after the nuclear assault that left the computer system Skynet in control of the world, Terminator Salvation follows John Connor (Christian Bale) as he grapples with both murderous robots and his superiors in the resistance, who aren’t sure they believe the prophecies that Connor is destined to save humanity. Into the midst of this struggle tumbles Marcus Wright (Sam Worthington, who would later star in James Cameron’s Avatar); the last thing he remembers was being executed in prison decades before. Baffled, he falls into company with Kyle Reese (Anton Yelchin, Star Trek) and a mute little girl who soon get captured--but Wright then meets and bonds with Blair Williams (Moon Bloodgood, Eight Below), a resistance fighter who remains loyal to the confused Wright even though Connor suspects he’s not what he seems--or what he believes himself to be. Terminator Salvation isn’t the astonishing synthesis of action and feeling that either The Terminator or T2 were. Despite this, Terminator Salvation has at least two skillfully orchestrated action sequences that will get your heart racing, and Worthington’s beguiling mixture of toughness and vulnerability gives his relationship with Bloodgood a genuine pulse. It’s imperfect, but compared with the hollow carcasses that most action movies (including Terminator 3) turn out to be, it’s worth seeing.
