Let's start with the obvious: Drones is a tonal high-wire act, and it wobbles. One scene has KPY Kuraishi's Mad Scientist delivering a monologue so deadpan it could double as a eulogy; the next has the film lunging for genuine dread in the doll house sequences. Sometimes the gear shift works beautifully. Sometimes it produces a lurch you can feel in your teeth.
What holds it together is the cast. Siddhi Idnani brings a lived-in weariness to a role that could easily have been a caricature, and Anjali Nair's Rush is the film's beating heart - cryptic, wounded, and never asking for your sympathy. Dravid Selvam's Kish is the audience surrogate, and he does the job well enough, though the film occasionally forgets he's supposed to be the protagonist. Devadarshini and Cinemawala Sathish as Koomapatti Madhavan get some of the film's best laughs, while Sassi Selvaraj's Cerlac Homes and RJ Deepak round out a supporting ensemble that clearly had fun on set.
Visually, the film is a triumph of resourcefulness over budget. The miniatures are tactile and gorgeously lit; the doll house interiors have a dusty, claustrophobic quality that lingers in your mind well after the credits. The witch's design is more suggestive than explicit, and the film is smarter for it. It's the kind of production design that reminds you that atmosphere costs less than spectacle and often buys you more.
Where it stumbles is in ambition. Mirdath wants to juggle five genres at once. He mostly catches them, but his hands are full, and the romance subplot in particular gets shortchanged - the cop's cursed love story is intriguing enough to carry its own film, and here it's reduced to a handful of scenes. Horror purists will find it too goofy. Comedy purists will find it too dark. Neither complaint is unfair.
The film's biggest sin, though, is its ending. Without spoiling anything, it resolves the central mystery in a way that feels less like a revelation and more like a shrug. A surreal film can get away with a lot, but it still owes you a landing.
