Terminator: Genisys might as well be called Terminator: Wibbly Wobbly Timey Wimey. Partly because of the brief-but-important presence of Doctor Who‘s Matt Smith, but mostly because the franchise is rebooting itself with the ol’ “let’s create an alternate timeline” gambit. I’m a sucker for time travel stories that draw on and then recreate the past, so the premise seems interesting enough: In 2029, at the height of the War Against the Machines, John Connor (Jason Clarke) sends his loyal lieutenant Kyle Reese (Jai Courtney) back to 1984 to save his scared little mother Sarah Connor (Emilia Clarke) from the scary Terminators. Except that when buck-naked Kyle shows up in the past, badass Sarah and an older Terminator (Arnold Schwarzenegger, embracing his age) already know about the machines and pick Kyle up on their way to stop Judgment Day.
