Feel free to pick and choose — you absolutely don’t need to use all of these in one meeting unless you want a full seminar at sea.

CHARACTERS: WHO’S ON THIS BOAT, REALLY?
––––––––––––––––––––

  1. Casting Call from the Open Sea
    When Keira Knightley walked on screen as Lo, did your brain say, “Yes, that’s her,” or “Who let this entirely different person onto my mental cruise ship?” Same for Richard, Anne, Carrie, etc. Who matched your mental casting from the book, and who felt like they were shipped in from a different novel?
  2. Lo 1.0 vs Lo 2.0 (Now With Fewer Demons)
    Book-Lo is anxious, exhausted, slightly self-destructive; Movie-Lo is still stressed but noticeably more competent and clear-headed. Which version pulled you in more, and why? Did you feel more protective of messy, unreliable Lo on the page, or did you prefer rooting for the more capable, put-together Lo on screen?
  3. Carrie: Femme Fatale, Co-Conspirator, or Cinnamon Roll?
    Carrie on the page has sharp edges and moral gray zones; Carrie on screen is softer, more victim than accomplice. Which Carrie made for a better story for you? Did the movie’s more sympathetic Carrie raise the emotional stakes, or did you miss the pricklier, more complicated version from the book?
  4. Anne Bullmer: Backdrop or Tragic Center?
    In the film, Anne gets more emotional weight and backstory. Did this shift change how you saw the entire scheme? Did you experience her more as tragic victim, quiet power player, or just a plot device with better lighting?
  5. The Extra Villains (Looking at You, Doctor)
    The movie adds and tweaks certain supporting characters (hello, suspicious doctor), trims others, and generally rearranges the deck chairs of the ensemble. Which supporting character upgrade or downgrade made the biggest difference for you — for better or worse?

––––––––––––––––––––
PLOT SURGERY: WHAT GOT CUT, WHAT GOT STITCHED IN
––––––––––––––––––––

  1. The Missing Home Invasion (And the Missing Hangover)
    The book opens with Lo’s flat being broken into and her coping badly — lots of fear, lots of drinking, lots of “is my brain trustworthy?” The movie tosses that overboard. Did you miss this backstory? Did removing it make Lo more credible… or remove a big chunk of what made her interesting?
  2. Unreliable Narrator vs Corporate-Conspiracy Thriller
    The novel keeps you wondering if Lo is misreading everything; the film more or less confirms early on that she really did see something and is being gaslit. Which version of the story hooked you more: “Is she losing it?” or “Why won’t anyone believe her?”
  3. Timing the Big Reveal
    In the book, the mystery stretches out with breadcrumbs and fake-outs; the movie seems to pop the lid off the main twist earlier, then shifts into escape/attack/survive mode. Did that earlier reveal work for you? Did it increase the tension (now you know the danger!) or drain it (mystery solved, now we just wait for the showdown)?
  4. The Ending: Choose Your Own Catastrophe
    Compare how the book and film wrap things up: who lives, who dies, who gets justice, who gets away with far too much. Which ending felt more satisfying on a gut level? Which felt more believable? If you could Frankenstein together your ideal ending using pieces from both, what would it look like?
  5. Subplots Lost at Sea
    Think about the book’s extra bits: emails, news clippings, outside-world reactions, small clues that snowball later. Which missing subplot, clue, or structural trick did you most wish the movie had kept? Conversely, did the movie add any scene or plot beat that you actually preferred to the novel?

––––––––––––––––––––
TONE & VIBE: HOW SPOOKY IS THIS YACHT, REALLY?
––––––––––––––––––––

  1. Atmosphere Check: Creepy or Just Chic?
    Did the film capture the book’s “luxury hotel slowly turning into a nightmare” feeling, or did it play more like a glossy vacation gone slightly wrong? Which medium made you feel the claustrophobia more strongly — pages or pixels?
  2. Genre Drift
    On the page, this often reads like psychological suspense with a side of paranoia. On screen, did it feel more like a straight-up mystery, an action-thriller, or something else? If you had to shelve each version in a video store (RIP), would they end up in the same section?

––––––––––––––––––––
SUSPENSE & PACING: EDGE OF SEAT OR CHECKING PHONE?
––––––––––––––––––––

  1. Which Made You More Anxious?
    Be honest: were you more tense reading about Lo pacing her tiny cabin while doubting her own mind, or watching her creep down dark corridors in Dolby surround sound? What kind of suspense hit you harder: internal “can I trust what I’m reading?” tension or external “oh no she’s going to die in that hallway” tension?
  2. Speed vs. Slow Burn
    Did the movie feel rushed, just right, or oddly uneven compared to the novel’s slower build? Were there specific sections (the initial scream/splash, the mid-ship investigation, the final confrontation) where you thought, “The book handled this better,” or “The film finally improved this bit”?
  3. Knowing the Story vs Experiencing It Again
    If you read the book first, did that kill the movie’s suspense, or was it fun waiting to see how they’d stage certain scenes? If anyone watched first and read later, did the book still manage to surprise them, or did it feel like a director’s cut in prose form?

––––––––––––––––––––
EYES VS. IMAGINATION: WHO TOLD THE STORY BETTER?
––––––––––––––––––––

  1. Scenes That Looked Better Than You Imagined
    Which moments did the movie absolutely nail visually? The blood on the balcony rail, the splash in the water, the storm, the too-perfect glass surfaces, the cramped cabins? Name one scene where you thought, “Okay, the camera really did beat my imagination here.”
  2. What the Book Did That the Camera Couldn’t
    Lo’s inner monologue is a huge part of the novel. What specific moments of her anxiety, doubt, or panic worked better in your head than they did on screen? Were there scenes where you thought, “If I hadn’t read the book, I’m not sure I’d fully get what she’s feeling right now”?
  3. Clues: Subtle Breadcrumbs vs Big Visual Hints
    The book uses small clues — keys, makeup, offhand comments, emails. Did the film handle clue-dropping in a satisfying way, or did it feel like it either underlined things too heavily or skipped over them entirely? Pick one clue that worked better in the book and one that worked better in the movie.

THEMES: BELIEVING WOMEN, BUYING SILENCE
––––––––––––––––––––

  1. Isolation, Literally and Socially
    Both versions trap Lo on a floating box with people who don’t believe her. Which medium made you feel that isolation more — the endless dark sea and locked doors on screen, or being trapped inside Lo’s spiraling thoughts on the page?
  2. Gaslighting & Credibility
    In the novel, Lo’s drinking, medication, and trauma make it easier for people to dismiss her. The movie tones that down but still shows her being ignored. Which approach hit you harder in terms of theme? Did the book’s messier Lo make the “believe women” angle more pointed, or did the movie’s clearer-headed Lo make the disbelief feel even more unfair?
  3. Wealth, Power, and Getting Away with Things
    How did each version handle the theme of rich, powerful people bending reality (and other people) to their will? Did the film sharpen that critique with its visuals and character tweaks, or did the book’s slower, more detailed build-up make the corruption feel more insidious?

OVERALL ADAPTATION VERDICT: HOW WOBBLY IS THIS GANGWAY?
––––––––––––––––––––

  1. “True to the Spirit” — Yay or Marketing Spin?
    The author has said the film feels true to the spirit of the book, even with big plot changes. Do you agree? If you had to explain to a friend what “spiritually faithful but plot-wise very different” means for this adaptation, how would you describe it?
  2. What Each Version Does Best
    If you had to give one gold star to the novel and one to the film, what would each be for? (Examples: “Best Internal Panic,” “Best Cinematic Splash,” “Best Use of Yacht Décor as Metaphor for Late-Stage Capitalism,” etc.)
  3. Recommend: Read, Watch, or Both?
    If a friend said, “I only have time for one version — book or movie?” what would you recommend, and why? Would your answer change if the friend loves psychological thrillers vs. fast-paced mysteries?
  4. Order of Operations
    If someone hasn’t experienced either version yet, what order would you suggest: book then movie, movie then book, or just one and done? How do you think the order would change the way they perceive Lo, the mystery, and the twist(s)?
  5. Final Club Gut Check
    On the scale from “perfect one-to-one adaptation” to “loosely inspired by,” where do you place this film? And more importantly: did you enjoy living in this story twice — once in your head and once on screen — or did one version make the other feel redundant?

Use, tweak, or mash these questions as needed — your club, your cruise.
