The Terminator series reboots itself with a partially new cast (Jai Courtney from "Spartacus: War of the Damned" as Kyle Reese, Emilia Clarke from "Game of Thrones" as Sarah Connor), a muddled script and an "alternate timeline." Seems it's 1984 again. Young Sarah Connor has been fully warned of Skynet's plans for Judgment Day and is protecting herself with a reprogrammed (and rather old) Terminator (played, of course, by Arnold Schwarzenegger). Then John Connor shows up from the future, only he's a Terminator now, and things get super confusing. See what you did, Star Trek?122 minutes PG-13.
