The existing Terminator series is a drawn-out tease of those incredible flashback sequences from Cameron’s original, with ragged human soldiers desperately fighting invincible war machines over the ruined corpses of their fallen comrades in a pitch black apocalypse. Yay!
 
Lesson for McG: That it’s finally time to make good on those promises. Not the bit before the war, not the bit where they stop the war happening, just man and machine gloving up and going at it.
