"The Girl on the Train" begins with Emily Blunt (in voice over) telling us her story as she drunkenly rides the train into Manhattan. She's obsessed with beautiful Haley Bennett, who happens to work as the nanny for her ex-husband (Justin Theroux) and his new wife (Rebecca Ferguson.) In a series of flashbacks and other points-of-view, we learn the nanny has a sex addiction and most likely an adulterous lover. Suddenly, the nanny disappears and we suspect Emily Blunt. But maybe... it's the psychiatrist, or maybe her husband did it, or maybe it's somebody else. "The Girl on the Train" begins as the dreamy semi-nightmare of an alcoholic, who's not quite sure what she's done. Emily Blunt does a fine job in the lead, nailing the confusion and pain of an alcoholic. The stories of the various characters, including the wife who replaced Emily and her ex-husband, as well as the psychiatrist treating the nanny add interest and thicken the plot. Unfortunately, the final third of this story doesn't quite match the promise of the beginning. One plot twist too many brought laughter from a friendly audience. I like director Tate Taylor ("The Help," among others) but he doesn't quite have the Hitchcock touch. 2½ stars. Rated "R" for sex, violence, murder, and nudity. Does it deliver what it promises? A whodunit. Is it entertaining? Pretty good, until it unravels toward the end. Is it worth the price of admission? Not great, but (sometimes) kinda fun.
