A good story but a not a great movie

Rating: 7/10 (23 November 2017)

The first thing to say is that I didn't read or watch that story before even did not watch story line or trailer before. So this movie provide me a satisfactory story. It is worth mentioning that I was thinking the friend of Hercule Poirot is the murder who has the ability to summon all the victim in the same train and familiar Hercule Poirot's inferential model which can mislead him easily. That makes me malicious surmise the only innocent people except Hercule Poirot. But the movie itself seem a little chaos for the too long prologue and too short supporting characterizations depiction which makes me too tired to remember almost 60% characterizations in a few minutes. At last, there are a few redundant plot in this movie. For instance, why those murder want to put the bloody clothe in Hercule Poirot 's case? Why the black lieutenant shout at Hercule Poirot "Why you didn't dead?" but those bugs doesn't affect the main line。 In conclusion, if you didn't read the story before then it is a worth watching movie.
