I've been watching the three episodes in this miniseries. While it's so far been reasonably faithful to Dame Agatha's original plot, various changes have been made with characters, settings, and business that just haven't set well with me. The book is one of her real masterpieces, but I think she'd roll over in her grave to know that her heirs are having her books "spiced" up with darkness and kinkiness wherever they can. Ordeal by Innocence changed the ending of Mrs. Christie's book (and thus the identity and motivation of the murderer), but I'll see when I watch the last episode if they've done that here, too (on the evidence of the first two installments, it doesn't appear like they're going to change it; it's such a shock trick that Christie pulls that nothing they could think of now would top it). While he's a fine actor, John Malkovich is not my idea of Hercule Poirot, and he doesn't seem urgent enough in the role. Also, Poirot was vain to the end, so he would NEVER have stopped dyeing his hair and mustache.
