I personally really enjoy this movie. I can understand peoples quarrels about the plot holes however because even though the concept is awesome there are a couple things that just can’t make sense in the movie. Other than that though it’s a film that you do experience as you watch it and the acting is very good too. It almost gives you a sense of a roadtrip movie because they’re scaling the length of the train for most of the movie. Definitely a movie i’d recommend. 4/5.
