Arnold Schwarzenegger in Terminator GenisysTERMINATOR GENISYS

Following some requisite, necessary backstory, Terminator Genisys opens in 2029 Los Angeles, where resistance leader John Connor (Jason Clarke) transports fellow revolutionary Kyle Reese (Jai Courtney) to 1984, where he's to hopefully prevent global apocalypse and protect John's mother Sarah (Emilia Clarke) from a murderous robot (Arnold Schwarzenegger). Upon arriving, however, Kyle finds that Sarah doesn't need saving and the robot isn't murderous, so off they go to 2017, where the planet is still imperiled, and John Connor himself proves to be the source of the planet's eventual ruin. After one of these whisks through the decades, Kyle says, "Time travel makes my head hurt," and time-travel movies generally make my head hurt, too. But for a fifth installment in an increasingly confounding series, this particular time-travel movie is actually a fair bit of fun.

Ellar Coltrane in BoyhoodBOYHOOD

Late in writer/director Richard Linklater's Boyhood - the finest movie yet by the creator of Dazed & Confused and the Before Sunrise/Sunset/Midnight trilogy - there's a simple scene between a mother and her son. The son, who is either nearing or has just turned 18, is heading to college and is packing a bag in his room; he and his mom talk while she pays bills in the kitchen. Then, seemingly out of nowhere, the mother starts weeping. Her son enters the room and nonchalantly asks what's wrong (this is hardly the first time he's seen her cry), and she replies with a litany of romantic, professional, locational, and maternal decisions that we've watched her make over the course of the film. She asks where all that time went. Her son, offering a slight smile of empathy, goes back to his room and continues packing. The mother buries her face in her hands, and says, "I just thought there would be more."
