In the very first Terminator film in 1984 Arnold Schwarzenegger assured us: “I’ll be back”. Arnie has proven to be a man of his word, returning again and again as James Cameron and his pals crank out yet another Terminator sequel. We’re now up to number six – and counting. This time the director is Tim Miller, who made the first Deadpool movie in 2016, but much of the old team remains in place.
