The wild card in all this "T"-ness is Marcus (Sam Worthington), a Death Row inmate-turned-cyborg. "You think you're human," Connor tells him, and indeed he does. More important, so do we: Marcus the machine is a far more interesting character than Connor.The world McG presents to us is scorched and hostile, and the action is startling and visceral. Significantly, "Terminator Salvation" (or, affectionately, "T4") takes itself far more seriously than its predecessors. That might have come off as pretentious but instead seems believable -- as believable as a movie can be, anyway, when it's about besieged humanity, occupational forces, rebel insurgencies, torture, lawlessness and warfare by remote control.Malkin comes alive to lift Pens.
