The Girl on the Train

I enjoyed Emily Blunt a lot in this movie.  She plays the alcoholic Rachel, who takes a train every day into NY city; and happens to pass  the very house she chose with her ex husband, that he, his new wife and baby  live in. They have a nanny, who turns out to be the wife of a neighbor.  While watching from the train, she observes some shenanigans. When the nanny disappears, the mystery  begins.  Emily Blunt’s Rachel was drunk that night and had got off the train to confront the nanny.  She wakes up at home, covered with blood and bruises.  She has no memory of what happened.  A detective, played by the always intriguing Allison Janney, investigates.  Then the nanny is found dead! Rachel has been violent before, could she be a murderer?  Things are not what they seem though, as all the main characters appear to be hiding something.  Even though there are some plot holes, and everything doesn’t exactly add up, it doesn’t harm the flow of the story, and Emily Blunt’s performance ties the whole movie together.  I read the book when it first came out and thought at the time it would make an interesting movie;I was not disappointed.
