“Death On The Nile” (**1/2 out of four) was a sleek follow-up to 2017’s “Murder On The Orient Express” about the continuing adventures of detective Hercule Poirot (Kenneth Branagh who also directed) who is called in to investigate the murder of a young heiress (Emma Mackey). Whodunit? Well- it could be her former partner (Armie Hammer), her childhood best friend (Gal Gadot) who stole him from her, or various other members of their inner circle party (Annette Bening, Tom Bateman, and others). Intriguing and alluring most of the way but final third becomes disappointingly flat when the story should shift into high-gear and film’s ending is somewhat of an abrupt letdown. Still overall worthwhile for Branagh and Agatha Christie fans. Gadot stands out in the magnificent cast.
