Welcome to the summer of 1985.I'm not talking about the theme of time travel, that staple of warm-weather movies. But there's something in the cinematic zeitgeist this summer that reeks of 30-year-old Drakkar Noir. From George Miller's "Mad Max: Fury Road" to "Straight Outta Compton," there's a distinct air of nostalgia in the multiplex for Reagan-era America.
