I miss crime shows like these although most of the credit should be given to Agatha Christie writing, very few shows manage to capture the essence of books they are adapted from.
I have watched a few Hercule Poirot movies and no one will ever top David Suchet portrayal. As a French speaker, I am always amazed that he was not a French speaker, his accent was spot on.
It's also funny to see all these British actors who got their start on Hercule Poirot from Damian Lewis to Emily Blunt and many more.
It's a bit like Law and Order where a lot of actors starred in the shows at their beginning career.
