I binged this on a transatlantic flight, and was initially quite impressed at the style and mood-setting, as well as the acting (though Bill Nighy is overexposed). But as episode 3 progressed, it became apparent that the entire premise of the plot (including the identity of the murderer and the motive) had been upset. I agree with all the other reviewers who said that Christie's name should be removed from the title. She supplied the set-up and cast of characters, but it wasn't the same plot. In fact, the ending felt more like one of Roald Dahl's Tales of the Unexpected than the resolution of a murder mystery.
