This story felt fresh, and the movie has properly thrilled me. The long build-up didn’t feature much acting, which was justified, but then there was action and acting in the final third. I’m not in the business of guessing twists, so I didn’t anticipate that turn. I have a slight feeling that some earlier moments didn’t fit it very well, but nothing obvious to me. And the final scene was a good touch, especially in contrast to an opposite story in a train in a different movie.
