Well, it's easy to see why the world wants more and more Agatha Christie - and here we have some fairly good fan fiction. Good acting and fairly good dialog. Though, here I have a slight problem with F-bombs being dropped here and there. Fortunately beeped out on PBS. Not really the sort of language one would expect Agatha Christie to use. At least the graphic set scenes that seem all to common in New adaptations has been left out. Though there is one or two scenes of some gore, but, seriously, if you've called Agatha Christie's novels "cozy" you haven't been paying attention. Pretty good plot twist. It'll pass in the dark if you give it a shove. OR, you could return to David Suchet as Poirot.
