The production is as great as it has always been. I also liked the portrayal of the tattered house and the dark scenes, in line with bad health of Poirot. My complaint is that the way Poirot committed his own murder was not nearly half as smart as the murderers Poirot caught, even worse it was not plausible; even if we accept that Poirot would indeed commit such a crime. Of course, there is nothing the production team could do about it, if they were not to grossly deviate from the source. I suppose, Christie was really bored of Poirot and could not think of a better way of getting rid of him. A disappointment overall, but not because of the team that produced the episode.

One has to be a brainless fan of Cristie and Poirot(in either the books or series who are somewhat different) to enjoy this episode.Episode is a faithful adaptation of the book in main story points, skillfully fitted to character of Poirot, with his blinkered morality, as developed in later 'darker' episodes of the series.From moral point of view, lousy logic used by Poirot to justify his murdering, and absolving of other murderers who have freely chosen to commit crimes, testify to either severe deterioration of his much referenced 'little grey cells', or Cristie's ironic revenge after developing a strong dislike for her character's smug pseudo rationality. Adapters did point to rather hypocritical moral compass of Poirot in several of the later episodes, such as 'The Clocks'. However they never seem to have the courage to carry it through to the end in any of them, and always dropped the ball before exposing the absurdity of Poirot's moral pontificating. They succeeded better when there is a distance between Poirot and characters going through a murder induced moral crisis, as in 'The Murder on the Orient Express'.Here too adapters fail to challenge Poirot's irrational murder. Nor do they leave the story at the superficial moral level Cristie displays in books. Unlike her, they raise the moral issues explicitly and seriously, but instead of confronting them in their complexity, they let Poirot getaway with absurdity.By the way, adapters in later part of series tried to imply that Poirot's blinkered morality is due to his pious Catholicism. However some of his moral positions do not fit with the Catholic teachings. If he is confused it due to his brain being confused.Actors were good in the episode, but unlike in almost all episodes in series, up to but not including final season, production design was bad.

"Curtain" is the last of the Poirot stories, which means the end of David Suchet's run as Poirot. To me, he will always be the definitive Poirot.Hastings, who has just lost his wife, is asked by Poirot to meet him at Styles, the site of a previous case thirty years earlier - their first.Styles is now a guest house. Poirot's health is failing, and he is confined to a wheelchair, due to his arthritis and bad heart. But he still has all his marbles. He tells Hastings that there is a murderer on the premises, and he needs Hastings to be his eyes and ears. The people there include the owners, Daisy and Colonel Toby Luttrell, a spinster, Elizabeth Cole, an aristocrat, Sir William Boyd Carrington, a birdwatcher Stephen Norton, a womanizer, Major Allerton, a chemist Dr John Franklin and his wife Barbara, her nurse, Nurse Craven, and Dr. Franklin's lab assistant, who just happens to be Hastings' estranged daughter Judith. One of these people is a killer. But can Hastings take his attention off his daughter long enough to help Poirot find him or her? Then the murders start. What does Poirot know? Can he solve his final case before his final curtain? A dark mystery, but a good one, with Poirot's illness permeating the entire episode. The murder in the end is actually the McGuffin - the big story is that this is Poirot's last case. My big complaint is that Miss Lemon and Superintendent Japp were not brought back for the episode.I know some people didn't like the turn this series took, and it's true, the seasons with Miss Lemon and Hastings were the best -- they had humor and lightness as well as mystery. But throughout all the seasons, there were always good episodes.Will be missed.

I am someone who has enjoyed many of Poirots episodes. The calm tone, good acting and decent dialogue had made it something that I was looking forward to watching. The final episode does not do any justice to the series. The lighting and decor appear to be purposefully bleak and depressing (unlike most other episodes where the color interplay always involves some strong nice colors as well). The plot and ultimate ending are simply unbelievable. Moreover, in my opinion this episode possibly casts a shadow over the morality of both Poirot and Hastings. There is other stuff too going on in this episode that is hardly worth mentioning simply because none of the characters seemed to have any particularly redeeming qualities. They were all kind of bland like the lightning and decor. All in all, very disappointed...
