There’s a point, somewhere around the third generic ghost jump-scare on a rocking deck, when you realize the most cursed thing in Mary (2019) isn’t the boat—it’s the script.
On paper, this should be at least interesting trash: Gary Oldman, Emily Mortimer, a haunted sailboat headed to Bermuda, family drama, witch lore, storms at sea. That’s a lot of good ingredients. What we actually get is the cinematic equivalent of microwaved leftovers: vaguely boat-flavored, occasionally hot in random spots, mostly bland, and you kind of hate yourself for consuming it.
Haunted Boat, Empty Head
We open with Sarah (Emily Mortimer) in an interrogation room, pulled from the wreckage of a boat and questioned by Detective Clarkson (Jennifer Esposito). This structure—“Let me tell you what really happened!”—is usually a device for tension and unreliable narration. Here it’s mostly an excuse to cut back to the present every fifteen minutes so you can be reminded that yes, this will eventually end.
Sarah insists Clarkson “won’t believe” what happened on board. Clarkson gamely asks her to try. The audience, however, will believe it, because we’ve seen this movie about a thousand times. It’s just that usually it comes with either better scares or less Gary Oldman pretending he isn’t bored.
Step One: Buy the Boat That’s Definitely Haunted
Sarah’s husband David (Gary Oldman), a helmsman on a tourist ferry, decides the best way to fix their marriage after her affair is to impulsively buy a salvaged sailboat that:
-
Was found abandoned by the Coast Guard
-
Is weirdly cheap
-
Already has the name “Mary” (just like their youngest daughter)
-
Gives off the distinct aura of, “We have killed people before and we’ll do it again”
Naturally, he buys it without consulting Sarah, because nothing says “let’s rebuild trust” like surprise demon yacht.
The family—David, Sarah, teenage Lindsey, and little Mary—along with David’s protégé Tommy and his friend Mike, patch up the vessel and head for Bermuda. The idea is to “bond” at sea. The script interprets “bond” as “trap everyone in a limited location so we can escalate supernatural nonsense and family arguments at the same time.”
Tommy takes a photo of the boat and sees a bright flash of light, which in a better movie would be an ominous clue. Here it’s just one more “spooky” thing that never quite lands.
Children, Imaginary Friends, and Crayon Foreshadowing
Little Mary quickly gets herself an imaginary friend: the woman who “lives on the boat.” She begins drawing disturbing crayon pictures, which shock absolutely no one except the characters, because by now we all know: if a kid starts drawing hangmen, demons, or bleeding eyes, you’re not on a pleasure cruise, you’re on a countdown.
Meanwhile, the first real sign this is going to be extra stupid arrives: Tommy stabs himself non-fatally, then attacks David, then gets committed to a mental institution on a nearby island. David and Sarah decide not to tell anyone, especially not Lindsey, Tommy’s girlfriend. This lies/secret subplot is meant to create tension, but mainly just makes them look like the kind of parents who would hide a zombie bite because “it’ll ruin the vacation.”
Tommy later hangs himself off-screen, and we’re supposed to be creeped out when Sarah notices Mary previously drew a hangman. It’s less chilling than it is mechanical: the movie keeps bringing receipts for its supernatural activity like, “See? It all connects!” Yes, we get it. Witch boat. Moving on.
Witches, Footprints, and Marital Collapse at Sea
Things escalate, if you can call it that. Footprints appear. Sarah gets locked in cabins. Nightmares hit. There’s an apparition of a woman. Mary smashes a glass into Lindsey’s face. David and Sarah argue constantly—she wants to turn back, he wants to press on, presumably to give the witch more time to work on their insurance situation.
Eventually, both parents separately research the history of the boat (apparently the demon didn’t password-protect its browser history), and discover that:
-
The previous owners vanished mysteriously
-
Everyone was headed on similar trips
-
The pattern strongly suggests the boat is possessed by the spirit of a drowned witch who’s trying to replace her children
At this point, any rational people would radio for help, aim the boat at the nearest coastline, and set the damn thing on fire from a safe distance. Instead, they kind of…have a tense conversation and then agree to turn back only after more bad things happen. Procrastination, but make it deadly.
Mike, Now With 100% More Witch
Before they can execute their belated good decision, Mike gets fully hijacked by the witch. Possessed Mike:
-
Destroys the sails
-
Dumps the fuel
-
Throws the satellite phone overboard
Thus ensuring that they are trapped in both a literal and narrative storm. The weather obliges by becoming Very Dramatic, and from here on out the movie is mostly people being thrown around by waves, shouting at each other, and occasionally being ghost-gaslit.
Lindsey sees Tommy’s ghost, who helpfully suggests she throw herself overboard—a kind of maritime peer pressure. She almost drowns herself, but David saves her. For a moment, you think, “Okay, maybe the emotional core is this father fighting to save his family.” The film then immediately resumes being a clumsy haunted-boat highlight reel.
Mike is locked up, gets free, knocks out David and Sarah, and tosses David into the ocean. He then does the same to Sarah, but she climbs back aboard because apparently the witch is terrible at quality control when picking human vessels. Possessed Mike is strong enough to wreck the boat but not quite competent enough to finish off the heroine.
David, not dead yet, reappears like a soggy deus ex machina and harpoons Mike. Sarah rescues the girls, straps them into life jackets, and sends them overboard. David steers the doomed Mary toward…something? Catharsis, maybe. Before Sarah can join the kids, the witch kills David in a jump scare that’s about as surprising as sunrise.
Sarah fires a flare at the witch, the boat explodes, the audience sighs, and we return to the interrogation room.
The Police Station: Now We’re Just Goofing Around
Back in the present, Detective Clarkson assumes what we’ve all been considering: Sarah is crazy and killed her own family. Frankly, the evidence would have to be very ghost-forward for anyone to conclude otherwise.
Clarkson decides Sarah shouldn’t see her daughters again (fair), and has her escorted away. But then she reviews the interrogation footage and sees video glitches. In horror language, this means “definitely demons” instead of the more realistic “get IT to look at that camera.”
She realizes Sarah is possessed by the witch. Clarkson goes to check on her, finds the escorting officer dead, and Sarah gone out the window. Outside, a storm rages, mirroring the one at sea, because once you commit to an on-the-nose symbol, you ride it all the way to the credits.
We’re left with a possessed Sarah loose in the world, and a franchise hook nobody asked for.
Wasted Cast, Wasted Potential
The truly haunted thing about Mary is how many talented people are trapped inside it.
Gary Oldman does his best with “stubborn dad who gets increasingly shouty on a boat,” but he feels weirdly miscast, as if he wandered onto the wrong set and decided to roll with it. Emily Mortimer carries the film more than it deserves, but there’s only so much nuance you can bring to, “I saw something in the cabin and then there were footprints.”
Jennifer Esposito’s detective is the only character who behaves like she’s seen a crime drama before, but even she ultimately has to bow to the supernatural twist. The kids are solid, but their arcs are thin. Owen Teague’s Tommy is essentially a walking victim foreshadowing generator.
Everyone seems to be acting in a different, better movie—one where the haunted boat concept is used to explore claustrophobia, guilt, and betrayal in an actual meaningful way. Instead, they’re stuck in this sea of clichés, treading water for 80-odd minutes.
Ghost Ship Lite
There’s an entire subgenre of “haunted ocean” movies—Ghost Ship, Triangle, The Fog, even Dead Calm flirted with it. Mary wants to join that pantheon but doesn’t understand what makes confinement-at-sea scary. It relies on cheap jump scares, repetitive dream sequences, and generic witch lore instead of building a thick atmosphere of dread.
The boat itself never feels like a character, just a set. The witch never feels like a presence, just a special effect occasionally wearing Mike as a meat-suit. The family drama is supposed to give emotional weight, but it plays like an afterthought: “Oh right, she had an affair. Guilt, blah blah, ghosts.”
It’s all so… shallow. Which is ironic for a movie set over the deep ocean.
Final Verdict: Abandon Ship
Mary is the kind of horror movie you forget almost as soon as you’ve seen it. It’s not awful in a gloriously entertaining way; it’s just a long, damp shrug with some decent actors trapped inside and a witch who feels more like a bad roommate than an ancient evil.
If your idea of a good time is watching Gary Oldman argue about turning the boat around while a child draws foreshadowing with crayons, this’ll do. Otherwise, if you want seafaring horror, there are much better vessels to board.
In short: haunted boat, yes. Scary movie, no. The real terror is realizing someone greenlit this, looked at the final cut, and said, “Perfect. Send it out to sea.”
