And Then There Were None/YMMV

• Non Sequitur Scene: The Harry Alan Towers film adaptations are full of such moments. For example, in the 1965 movie, Lombard and the butler get into a random fistfight that lasts about one minute before the judge says "Now, now, that's enough"...and it is. It is promptly forgotten, and never brought up again.
  • Or the 1989 movie. There are several moments that fit this trope, but one that stands out in particular is the usual "Marston plays the full rhyme on the piano" scene that is usually in each adaptation (and ends up being crucial to introducing the rhyme to the audience)...except instead of actually playing the rhyme, Marston plays a few seconds of "Mad Dogs and Englishmen". Why? No one knows. And no one spends their time speculating on it, either.
• Crowning Moment of Funny: Blore's death in the 1945 film.

"I get it!"
*splat*

• Crowning Music of Awesome: The opening theme to the game. Whether you love or hate the game, hell, even if you hate it, you can't deny that the theme does an excellent job of capturing the creepy atmosphere.
• Draco In Leather Pants: Lombard seems to be gaining himself a bit of a fandom on Deviant ART.
• Hilarious in Hindsight: MacArthur.
• Magnificent Bastard: The murderer.
• Misaimed Fandom: Let's just say that if the internet had existed when the book was first published, or if Agatha Christie had lived long enough to see the internet, she would have done a lot of head-desking at the discovery of how fans found some of her most intentionally despicable murderers to be sympathetic.
  • Christie was fond of having a sympathetic character turn out to be a murderer, because these types of characters tend not to be suspected by the reader. However, the notion that fans would still find these characters sympathetic after their guilt had become clear beyond a doubt would certainly make her mind boggle.
  • Philip Lombard seems to be gaining himself a bit of a fandom in recent years, if the artwork pairing him up with a Mary Sue on Deviant ART is any indication. Hmm...Lombard in leather pants, maybe?
• Misblamed: Rene Clair, director of the 1945 film version, received a lot of criticism for changing the ending of the book. A lot of people did not realize that the film's ending came from Christie herself, having changed it upon adapting the novel for the stage in 1943.
• Moral Event Horizon: Arguably, what all the guests' crimes basically are. Emily Brent is the one fans vilify the most for her crime. Agatha Christie possibly knew about this and made her even more horrifying in the play by giving her a monologue where she admits she completely and totally broke poor Beatrice down by more or less implying she's a slut whom no one will ever take in and that the father of her child would never dream of marrying her. Even Vera Claythorne is horrified, and that's saying something, considering what she did. Interestingly enough, fans don't give her as hard of a time as they do Miss Brent, as she is mildly sympathetic, but of course, not everyone feels the same way.
  • And then there's Philip Lombard, who is something of an Anti-Hero in the book regardless of what he did. The Russian film version, however, changes that. He ceases to be even a semi-likeable character when he rapes an already mentally unstable Vera Claythorne, and it is subtly implied this plays a part in her breakdown at the end.
    • Lombard's event horizon is subverted in the original black & white movie, in which it is revealed that he is not Lombard but a friend of his impersonating him after the real Lombard recently committed suicide.
• Narm:
  • Vera Claythorne's internal monologues in the book seem like this to some.
  • Anthony Marston's demise in the game.
  • Rogers' reaction to the death of his wife in the 1989 film.
• Romantic Plot Tumor: Averted in the original novel, and to a certain degree in Agatha Christie's stage version and the 1945 movie as well, but the Harry Alan Towers adaptations put much more focus on the romantic subplot between the two survivors than on the actual mystery itself.
  • And the game. Dear Lord, the game...
• They Just Didn't Care: All three Harry Alan Towers films changed the locale of the story, as well as most of the character names, for no identifiable reason.
  • Some of the character names were changed to accommodate the nationality of the actor playing the role; for instance, Anthony Marston became Prince Nikita Starloff when Russian-born Mischa Auer was cast in the 1945 version. However, for many of the roles, no discernible reason for the change exists. (Why was Vera Claythorne's name changed to Ann Clyde in the 1965 version?) Lombard's first name was changed to Hugh in the 1965 version as a nod to actor Hugh O'Brian, but it inexplicably remained Hugh in the 1975 version, which featured Oliver Reed in the role. William Blore is the only name to remain consistent through all the adaptations.
• Values Dissonance: Philip Lombard justifies the abandonment of the natives with what amounts to "What Value is a Non-White?" (and Vera seems to agree—Emily Brent, of all people, calls her out on it!); he also refers to Isaac Morris as a "little Jewboy" and figures Morris called his bluff on his need for money because Jews just know these kinds of things.
  • The need to change the book's title (and the rhyme itself) over the years and the excision of terms like "nigger in the woodpile" also count.
• The Woobie: Many, many fans find Macarthur to be the most sympathetic of all the guests. He was pretty much dead before he came to the island.
