There is a specific sound a studio horror picture makes when it decides to stop trying for atmosphere and simply settle for noise, and if I'm honest, the sound engineer on Alone must have had his finger glued to the panic button for roughly ninety percent of the running time. Let's start with the hair because nobody ever talks about the hair in these things. Karan Singh Grover spends the entirety of this film with a blowout so aggressively lacquered against the humidity of Kerala that you spend half your time wondering what brand of styling gel survives a demonic possession. It is a small thing, but it bugged me from frame one. Bhushan Patel is not a filmmaker who trusts silence, which is perhaps the first and most fatal error you can make when adapting a Thai chiller about conjoined twins into something palatable for multiplex audiences raised on a diet of jump scares. The original 2007 film by Banjong Pisanthanakun and Parkpoom Wongpoom had a quiet, rotting patience to it that got under your skin precisely because it refused to raise its voice. Here, every time a ghost walks past a window, the score hits you over the head with an orchestral crash that sounds like a grand piano being dropped down a concrete stairwell. Hindi films have long had a complicated relationship with subtlety, sure, but this particular brand of sonic bludgeoning feels less like genuine dread and more like an endurance test designed for people who check their phones every thirty seconds anyway.

The screenplay by Milind Gadagkar takes the premise of two sisters joined at the hip and turns it into a domestic melodrama wrapped in a cheap shroud, complete with all the standard tropes you expect from commercial Bollywood releases of that vintage. Sanjana and Anjana share a body until a messy, tragic separation surgery leaves only one alive, or so the surviving twin would have you believe when she returns to her ancestral home with her suspiciously patient husband Kabir in tow. Grover plays Kabir with the kind of placid, handsome blankness that usually suggests an actor who was cast entirely on the strength of his gym routine rather than his ability to react to things that aren't there. When his wife starts seeing her dead sister in the bathroom mirror, his primary mode of emotional expression is a furrowed brow that never quite crosses the threshold into genuine panic. Bipasha Basu pulls double duty as the dueling siblings, and while she actually manages to carve out distinct physical postures for both women—one hunched and defensive, the other smooth and predatory—the editing chops them up so fast that you barely have time to appreciate the physical labor involved in pretending to be stitched to another human being. The visual effects team tries their best with the split-screen composites, but too many shots feature hazy lighting and convenient shadows designed to hide the digital seams where the body double was stitched into the frame.

There's a strange structural sluggishness to the middle act that feels less like mounting tension and more like narrative treading of water, as if the director realized he had ninety minutes of story and only sixty minutes of actual plot to get through. We get flashbacks to college days where the sisters fall for the same man, which turns the whole haunting into a garden-variety tale of jealousy from beyond the grave, stripping away whatever physiological horror the initial premise promised. It reminds me a bit of Ram Gopal Varma's Phoonk in the way it mistakes the repetition of slamming doors and flickering lights for psychological progression. The cinematography by Pravin Bhatt relies heavily on a jaundiced, tea-stained color grading that makes every indoor location look like it was shot inside an old cigarette tin. When the camera finally goes outside into the mist-shrouded rubber plantations, the landscape briefly comes alive with an authentic, damp menace that the rest of the production desperately needs. Yet the moment we return to the sterile interiors of the couple's cavernous modern mansion, the lighting goes flat again and the actors are forced to deliver exposition against walls that look like they were painted an hour before the cameras rolled.

Hindi movies have historically struggled with how to integrate supernatural logic into family dynamics, and Alone solves this problem by simply refusing to explain any of the rules governing its own ghost story. Can the dead sister manipulate physical objects, or is she just living inside her surviving twin's guilt-addled imagination? The film can't decide, so it flirts with psychological thriller tropes one minute before indulging in full-scale poltergeist nonsense the next, having furniture slide across hardwood floors while Kabir sleeps right through it on a sofa three feet away. Grover has this recurring reaction shot where his eyes go wide and he stares into the middle distance, and it appears in almost every single sequence where something spooky happens to the plumbing or the electricity. It's a mechanical performance that feels dubbed even when you know it is live sound, largely because the dialogue has been written with such wooden economy that nobody could ever make it sound like human speech. Basu fares better when she gets to snarl and scratch at doors, shedding the glamorous persona that defined so much of her career for a gritty, unkempt desperation that almost justifies the ticket price.

The soundtrack features a couple of obligatory romantic numbers that grind the narrative momentum down to a dead halt every time they appear on screen, pulling us out of whatever meager atmosphere the filmmakers managed to build in the preceding scenes. That particular convention of commercial cinema is hard to shake, but dropping a sun-drenched beachside ballad right after a character has nearly been choked to death by a supernatural twin feels like a bizarre editing choice that betrays zero confidence in the horror elements. There is no sense of cumulative dread. Every scare is treated as a discrete, isolated event with its own hard stop and reset button, meaning the characters are just as surprised by the next ghost sighting as if nothing had happened five minutes prior. We watch the husband investigate a creaking floorboard, watch the wife stare blankly into a closet, watch the CGI specter lurch toward the lens with an open mouth, and then we do it all over again in the next room.

Basu puts her back into the physical transformation required to play a haunted survivor, throwing herself onto tile floors and contorting her limbs with an abandon that deserves a better movie built around it. The trouble is that the script treats her trauma as a plot device rather than a lived reality, rushing past the genuinely fascinating implications of body horror to deliver cheap thrills that wouldn't frighten a ten-year-old on a sleepover. When the credits finally roll, you are left with the distinct impression of a project that was assembled in a boardroom rather than imagined by a storyteller, checking off horror clichés the way an accountant fills out a ledger. It's a competent enough time-pass if you happen to be catching it on late-night cable with the volume half down, but it leaves almost zero imprint on the memory once the screen goes black.
