Worst remake ever!

Rating: 1/10 (4 November 2019)

I loved the 1974 version of that story directed by Sidney Lumet. Back then, the stroy was plausible, and the characters were interesting and the plot males sense. In the 2017 version, I was expecting to see the same characters, but unfortunately some were simply replaced in prder to fill some affirmative action quota I imagine.
The historical innacuracies are immense, for example the fact that you had black and white interracial couple on the train, and the black man was a "respectable" doctor who was some sort of soldier before. The strory doesn't fit, since in order to go to medical school (which was way more elitist back then), you needed years on prep school or private tutoring. Besides, there were black doctors in the US, bit they were part of an elite, and attended the Historical Black colleges and Universities. Talking about affirmative atcion in tye movie, in the end we see a very dark skinned black soldier posing as Yugoslavian, a nation so intolerant that they were killing their own neighbours because of a different accent (most recently in the 90s, especially Bosnia).
Then, we had a Hungarian Prince married to a Jewess girl, when in nobility, we know that interreligious weddings are gery often forbidden (in the UK, there are rules against an Anglican marrying a Catholic for example). That didn't happened then, and even nowadays there ar no incidents of interfaith families in the high nobility (by the room he got, we see the prince was a hot shot).
Then there are the German bashing moment that every Hollywood movie insist when in the year 1934, the country was still a democracy, and the references to "the war" are annoyingly every minute, when Agatha Christie's books deal mostly with the upper classes, who are not involved in conflicts.
Again, the director includes some token characters: a mexican chauffer, a german assistant, and a Russian countess, who were almost absent from the plot, and could be better used. There are action scenes that are totally unnecessary.

In short, the movie sucks!
