The USP of the this movie is Teresa Palmer's brilliant acting, her non-glamourous look of a tourist in a famous city but new to her right from the first scene where she lands on to the station and comes out of the subway will catch your attention. She carries this entire captive movie on her shoulders and makes it watchable. There are just a handful of characters and it was mostly upon her performance the film depended on, and she delivers. 6/10.
