Movie previews, in the theater, on TV, a computer, or phone, are supposed to get you in the theater. They have to be memorable, and for that to happen they have to be familiar yet unfamiliar. I'm in the thick of reading The Girl on the Train and the movie has opened to generally bad reviews. The preview itself shows a combination of Rear Window and Fatal Attraction. The story reflects what many of us experience on our morning and evening commutes: we wonder about others greet briefly before moving on. So the premise is strong enough and should appeal to a wide variety of people who do the same thing as part of a routine no matter how many work from home or remotely. The story is also circular, gradually encroaching on a climax we sense coming but remains elusive. This is all fine and dandy. The director, Tate Taylor, did the splendid The Help and Get On Up. This may be a case of The Devil's Candy, when Julie Salomon followed Brian De Palma in making The Bonfire of the Vanities, where a studio influences a production start to finish. There a director gradually lost control. I don't know, but somewhere the story, in trying to appeal to its wide audience, lost its specificity, which will alienate its wide audience. The book is particular and creates admirable, flawed humans who soldier on in trying times no matter the point of view. That's why the book matters, the movie may not.
