There something comforting about an Agatha Christie mystery, though I have never tried to quantify why.
Before now, that is.
I think that what drew me to them originally was the logical way the stories were constructed and the way the mystery unfolded. Typically you put a group of strangers in a situation where there’s no readily available avenue of escape, and have one of them die by sinister means.
No one can be trusted (other than the detective, that is) It’s not a particularly innovative formula but I find–when they’re done well–them to be endlessly entertaining
In fact, my only issue with the 2017 version (if there haven’t been at least three or four versions there haven’t been any) is that Kenneth Brannagh is playing Hercule Poirot, who happens to look nothing at all like the character as described by Agatha Christie.
Peter Ustinov, who played the fastidious Belgian detective in Death On The Nile, was better (visually speaking) though neither can compare to David Suchet, who in my mind will always be the definitive Hercule Poriot.
