‘The Girl On the Train’ delivers a riveting ride

A juicy and jolting adaptation of Paula Hawkins’ best-seller, “The Girl On The Train” (2016, Universal, R, $30) has enough plot for a mini-series but director Tate Taylor (“The Help”) keeps it all relatable and deeply human.

Chief among the film’s strengths is Emily Blunt who delivers a raw and unsettling turn as Rachel Watson, an alcoholic whose life begins spiraling out of control after she loses her job and spouse (Justin Theroux). Obsessed both with her ex-husband’s new wife (Rebecca Ferguson) and a seemingly perfect woman named Megan (Haley Bennett) who lives down the street, Rachel begins to suspect that she might be responsible for Megan’s sudden disappearance.

“The Girl on the Train” delivers a riveting ride. Extras: deleted scenes, featurettes and commentary by Taylor.

Zero Days (2016, Magnolia, unrated, $28): Riveting from start to finish, this documentary is a deep dive into the burgeoning world of digital warfare. Filmmaker Alex Gibney (“Taxi to the Dark Side”) begins with the story of the Stuxnet virus, a malware program reportedly launched by the United States and Israel to disrupt an Iranian nuclear facility. While Stuxnet worked temporarily, frustrating Iranian scientists, it also set a precedent for what constitutes a justifiable cyber attack. “Zero Days” argues for more transparency involving digital warfare as every country in the world, including Iran, grows more and more capable of shutting down its enemies’ power grids — and more — with a single keystroke. Extras: featurette.

Ace The Case (2016, Gravitas Ventures, PG-13,

$20): If “Rear Window” had been directed by Harriet the Spy, it would look at lot like this hit-and-miss effort about a youngster (Ripley Sobo) who witnesses the kidnapping of her neighbor and turns for help to a sharp-eyed police detective (Susan Sarandon). Sobo is a likeable actress whose efforts to play sleuth both with or without Sarandon are mostly fun and watchable. But this mystery doles out too much screen time to the bumbling criminals and an enforcer hired by the victim’s father. Writer/ director Kevin Kaufman also has problems finding the right tone for this outing, which is too violent for kids and too silly for adults. Extras: featurette.

The Free World (2016, IFC, R, $25):

Fresh from a stint in prison for a crime he didn’t commit, Mo (Boyd Holbrook) risks his freedom by sheltering an abused wife (Elisabeth Moss) who’s

COURTESY PHOTO just murdered her husband. There’s not a lot of subtlety in this Southern-fried romance which lays everything on too thick. But Holbrook and Moss have so much chemistry and are capable of finding hidden complexity in their roles that it almost doesn’t...
