Robert is a lonely audio engineer. After much research he manages to develop a sound frequency that immediately puts anyone who hears it into an hypnotic trance and makes them totally bend to his commands. He immediately starts using the device to influence his neighbours, initially sparingly but then constantly. What could possibly go wrong?Novel idea. Pretty much plays to our fantasies of having some sort of magical power that allows us to control others. The scene-setting and the initial use of the device was quite interesting and even amusing at times.A pity then that the plot doesn't really go anywhere. With everything nicely set up for something profound or, at least, entertaining, the movies drifts from about the half-way mark. Instead of building on the start, we pretty much have the same scenarios being played out over and over again. The movie does ultimately find a direction, but it's a random one, one that is not developed or justified at all by what came before. Quite bizarre and random ending.Worth seeing for the first half. Second half is disappointing.

Wonderful, thoughtful black comedy.

Darkly comic sci-fi drama about a very creepy (and very damaged) man who may have discovered a frequency that lets him hypnotize others. Often does not go in the directions one would expect. Well worth a watch.

Quite different and organic though it went through all the steps you thought it would go. Would have been nice to see a shift towards the end in that aspect.

An amazing piece of cinema considering its huge budget constraints!

Great storyline. Perverse but it would make a great remake in English with some seasoned actors and actress's.

LFO is a tale of ordinary madness, an origin story for a superhero (or villain), and an allegory of power and its abuses

The uniquely Swedish "LFO" is as droll as it is uncomfortable.

LFO is ambitious and bizarre enough to work on levels that some might not hear ringing clearly, yet its presence cannot be ignored.

Tublén's wryly banalised, tone-perfect scenario builds with disorienting humour to a bleak, thought-provoking close that suggests it is ultimately impossible to escape one's own darkest interiors.

Tublen's last-act feels like a purposefully cheap gag, but LFO is nevertheless a consistently humorous lo-fi sci-fi story.
