Every so often, a horror movie comes along that dares to ask the big questions — like “What if ghosts were actually time travelers?” or “What if Ali Larter was trapped in a film so confused it thinks The X-Files is a rom-com?” The Diabolical(2015) is one of those brave, baffling attempts. It aims for terrifying, lands on tedious, and somehow crashes headfirst into the realm of accidental comedy.
Directed by Alistair Legrand, this movie tries to mash up Poltergeist, Looper, and a lifetime original about a single mom in foreclosure — and the result is like watching a haunted blender explode.
1. The Setup: Domestic Bliss Meets Dimensional Nonsense
We open on Madison (Ali Larter), a single mom living in a suburban home so bland it could be used in a real estate training video. She’s struggling financially, juggling two kids, and dating her son’s science tutor — which is one way to make sure parent-teacher conferences get really awkward.
Then, one night, things start getting spooky. Chairs move, shadows flicker, and a bald ghost-man shows up covered in blood, looking like Voldemort’s out-of-work cousin. Madison reacts not with terror, but with the weary energy of someone who’s already had three glasses of wine and just wants to finish Bridgerton.
Her kids start seeing the apparitions too, and every night becomes a carnival of jump scares and confusion. Paranormal experts come and go, none of them helping, all of them billing by the hour. Madison’s house is like a revolving door for underqualified ghostbusters.
2. The Science Fiction Twist Nobody Asked For
At first, The Diabolical seems like it might settle into being a forgettable haunted-house flick — but no. Around the halfway mark, the movie remembers it also wants to be science fiction, because apparently ghosts weren’t interesting enough.
It turns out the apparitions aren’t spirits at all — they’re failed human teleportation experiments from the future. Yes, you heard right. The house isn’t haunted; it’s just accidentally parked on a tear in the space-time continuum.
Suddenly, Madison’s boyfriend Nikolai (Arjun Gupta) reveals he used to work for an evil research company called CamSET. He explains, with the intensity of a man who just read half of a Wikipedia article on quantum physics, that the bald ghost-man might actually be a time traveler from forty years ahead.
This revelation should be mind-blowing. Instead, it’s like watching someone explain the plot of Tenet after a head injury.
3. Meet the Bald Man: A Horror Icon Who Never Was
Let’s talk about the bald man.
He appears early on, covered in blood, bound, and perpetually screaming. He doesn’t walk so much as stumble, like a drunk mall Santa at closing time. He’s supposed to be terrifying, but after the fourth time he teleports into a hallway and grunts menacingly, you start to feel bad for him.
He’s not scary — he’s exhausted. If monsters could file for workers’ comp, this guy would be first in line.
The real kicker? He’s not a ghost. He’s not even a villain. He’s Jacob, Madison’s son — from the future. So, yes, the film’s big emotional twist is that this woman has spent most of the movie trying to murder her own child.
There’s something darkly poetic about it — like Oedipus Rex, if Oedipus had a laser gun and unresolved trauma from a CamSET internship.
4. Ali Larter vs. Physics, Logic, and Script Continuity
Ali Larter deserves better than this. She’s a capable actress, but here she’s fighting not just ghosts and time rifts — she’s fighting the screenplay itself.
Madison’s emotional arc is supposed to be one of resilience and motherly courage. Instead, she just looks perpetually tired, as if she’s been trapped in a Home Depot commercial directed by David Lynch. Every time she screams or cries, it feels less like fear and more like the cumulative fatigue of reading this script aloud.
One moment she’s protecting her kids, the next she’s crafting Home Alone traps for temporal anomalies, and the next she’s discovering time travel on Google. By the final act, she’s simultaneously a paranormal investigator, physicist, and mother of the year — all while wearing jeans that somehow never stain during all the blood and screaming.
5. The CamSET Conspiracy: Because Every Movie Needs a Shady Corporation
If you thought the evil lab subplot sounded generic, that’s because it is. CamSET might be the least convincing scientific organization in film history. Their sinister plan? Vaguely “experimenting with teleportation.” Their moral compass? A black hole.
By the time we learn that Future Jacob was lobotomized and used as a test subject, the movie’s tone has whiplashed so hard it could sue itself. It’s as if The Conjuring suddenly decided to be Fringe, and then halfway through thought, “You know what this needs? Family drama and OSHA violations.”
6. The Time Travel Reveal: More Confusing Than Moving Furniture
Let’s take a moment to unpack the twist — because clearly, the writers didn’t.
So, Future Jacob was captured by CamSET after trying to destroy their lab (for reasons unknown). They lobotomized him and sent him back in time as a failed teleportation experiment. That means the creature terrorizing Madison’s family is her son, mutilated and trapped in a time loop.
When she realizes this, she lies down beside him in a tender, almost romantic gesture — which, given the context, is the creepiest Freudian thing since Norman Bates redecorated his mom’s bedroom. Then she’s magically teleported to the future, healed by off-screen science, and sent back home to stare into space while her living son hugs her.
It’s not so much an ending as it is a cry for help from the editing room.
7. Horror Without Horror
The biggest sin The Diabolical commits isn’t its messy plot — it’s that it’s boring. For a movie about interdimensional horror and maternal desperation, it has the pulse of a damp sponge.
Every scare feels rehearsed. Every revelation feels accidental. Even the visual effects — all flickering lights and shimmering ghosts — look like someone discovered the “distort” filter on After Effects and thought, “That’s cinema.”
It’s not that the movie is badly made; it’s that it’s made with such earnest seriousness that you almost wish it were worse, just for entertainment value.
8. Dark Humor in the Wrong Places
There are moments of unintentional comedy sprinkled throughout, mostly thanks to dialogue that sounds like it was written by an alien imitating human speech. Lines like “You can’t leave — the house makes you sick!” or “He’s from the future!” are delivered with deadpan sincerity, as if that explains everything.
When the police show up, they’re immediately killed by the bald man in what might be the most anticlimactic action sequence ever filmed. You could blink and miss it — which, honestly, might be for the best.
Even the ending — Madison staring blankly into the void while her son hugs her — feels like the audience’s own reflection. You, too, have seen things. You, too, will never get that time back.
9. The Real Diabolical Thing Here
The truly diabolical force in The Diabolical isn’t the ghost, or the time travel, or even CamSET. It’s the script — a cursed artifact that devours logic and joy in equal measure. It’s what happens when filmmakers can’t decide between paranormal horror, family drama, and sci-fi thriller, and instead choose “yes.”
The result is a Frankenstein’s monster of genres — stitched together, twitching, and begging for release.
10. Final Verdict: A Temporal Tragedy
The Diabolical tries to be profound, but ends up as a cautionary tale about ambition without coherence. It’s not terrifying, not thrilling, and not particularly diabolical — unless your definition of horror is watching talented actors wrestle with pseudo-science for 90 minutes.
The future version of me would travel back in time just to stop myself from pressing play.
Rating: 3/10 — Time travel’s biggest crime since The Butterfly Effect 2.
