Branagh rendering of the "Orient Express" was awful, "Death on the Nile" was passable but by the third Agatha Christie based movie, he shaped up. It is quite well-wrought thriller, very loosely based on the "Halloween Party" by Agatha Christie, or so I was told. The only shortcoming of this griping movie is that thought process of Poirot is not shown and his conjectures about a crime come from nowhere. Yes, and Poirot retiring into a Venetian palace is over the top.
