Rightly or wrongly this was a story inspired by the original Agatha Christie novel rather than the story itself. Yes it was very different BUT I still found it very watchable. I watched it over 3 consecutive nights and wanted to watch to the end despite knowing 'who dunnit'. I was intrigued to find out about the demons Poirot was wrestling with from his past. It was a tad overlong though, I think two episodes with less padding might have been better, and why they didn't just make something similar with a new detective we didn't know is unfathomable as they made it almost unrecognisable anyway. It would have worked just as well as I thought John Malkovich was very good.
