The movie is a 2017 American mystery drama film following a murder case on a train. One of the passengers is Hercule. He is the last resort to solve the case.
Still, Branagh clearly has fun with the eccentric nature of the Poirot character, whose gift of insight is a blessing when it comes to solving crimes but a curse in its effects on his daily existence.
There's no reason to see this tiresome, forlorn, forgettable whodunit, which derails almost from the get-go, long before the snow-bound, stranded strangers begin to suspect one another of murder.
Even if you're familiar with the story (particularly the memorably lavish 1974 movie), you'll get caught up with what is one of the best murder mystery plots of all time.
To return to why Murder on the Orient Express was remade: Beats me. Maybe it's someone's idea of counterprogramming when every other film in the multiplex is for kids or yahoos. Maybe it's a tax shelter.
Like Poirot, Branagh - the director - is immensely attentive to fact and detail, including drawing a robust performance out of Branagh - the actor - playing the quirky detective with a mix of cheeky humor, vim and vigor.
