Should you watch it?

Watch it if you like tense, grimy crime thrillers where the mood of a place matters as much as the plot, and where a lead character's split loyalties carry the suspense.

Skip it if you want a fast, plot-driven thriller; this one lingers on atmosphere and character, and its noirish, sometimes sleazy texture may feel slow or unpleasant.

What it asks of you: Under two hours, it settles in and rewards patience, with a dark, unsettled tone and a steady focus on one woman's divided attention rather than constant action.

If you liked this

Blue Steel1990

Kathryn Bigelow's film about a rookie cop whose gun ends up in a killer's hands. Tight, violent, and equally interested in how police work corrodes the people doing it. Similar moral vertigo.

But It's more action-oriented than psychological—if you want introspection over gunplay, this skews the other way.

Body Double1984

De Palma's obsessive thriller about a man watching a woman through a window, then drawn into her murder. Perverse, visually audacious, and completely uninterested in reassuring you morally. Same murky entanglement.

But It's stylish to the point of detachment. Some find the voyeuristic setup exploitative rather than thrilling.

Jagged Edge1985

A lawyer defending a man she suspects murdered his wife. Erotic tension, courtroom procedure, and the constant question of whether you're rooting for the guilty party. Addictive ambiguity.

But The plot hinges on a twist that requires you not to think too hard about the logistics. Doesn't fully hold up on rewatch.

The wildcard

Something you would not have found on your own.

Klute1971

Both center on a woman whose sexuality is the currency through which the plot moves; both treat that as tragedy rather than entertainment.

Sutherland and Fonda in a 1970s procedural about a missing man and a sex worker drawn into his disappearance. Deliberately slow, psychologically precise, and uninterested in your comfort. A direct ancestor to Impulse's moral confusion and sexual vulnerability.

But It's glacially paced by modern standards and refuses to provide catharsis. The misogyny of the era also creeps through in ways that can't be redeemed.

Blood Simple1985

The Coens' debut: a Texas noir where mistaken identity and paranoia lead ordinary people into murder. Gorgeously shot, icily plotted, and morally pitiless. Same atmosphere of moral free-fall.

But It's deliberately paced and won't give you the satisfaction of answers. The violence is shocking and stays with you.

Tightrope1984

Eastwood as a cop investigating a serial killer while leading a secret life that mirrors the killer's desires. Uncomfortably good at exploring how close the detective comes to the criminal. Raw and genuinely unsettling.

But The sexual politics are very much 1984—some of it plays as regressive now, intentionally or not.

Maniac Cop1988

James B. Harris's adaptation of James Ellroy's novel: a brutal LAPD detective and a murder case that keeps widening. Ugly, procedural, no heroes. Captures the grinding demoralization of police work.

But It's deliberately unglamorous and the hero is genuinely unlikeable. If you want someone to root for, this isn't it.

The Killers1946

Siodmak's classic noir: a man is murdered and nobody—including the victim—seems to care. Stylish, fatalistic, and built on the same principle that people are complicit in their own ruin.

But It's in black and white and the pacing is patient. Requires you to sit with mood rather than plot momentum.

Internal Affairs1990

Andy Garcia vs. Richard Gere in a cat-and-mouse game about police corruption and sexual manipulation. Released the same year; similar grime and moral murk. Tighter plotting than Impulse but less interesting.

But It resolves more neatly, which some find satisfying and others find dishonest about how power actually works.

Bound1996

The Wachowskis' debut: a woman and a woman's lover con her way out of a mob situation. Sex, crime, and two people lying to everyone. Visual and kinetic in ways Impulse isn't, but the same engine.

But It's slicker and more fun—if you want moral complexity rather than thrills, you might find it too stylish to care.

Memento Mori1992

Same core idea: a female investigator whose professional and personal selves are weaponized against her, with no resolution that leaves anyone safe.

A Soviet/Russian TV miniseries about a woman cop investigating murders while her own life fragments. Shot like a fever dream, morally uncompromising, and utterly indifferent to American narrative comfort. Impulse's international sibling.

But It's bleak in ways that make even dark American thrillers look quaint. Finding it with subtitles takes work, and it demands emotional stamina.

Bad Lieutenant1992

Both treat police work as a gateway to moral dissolution; Bad Lieutenant shows what happens when you stop pretending it isn't.

Abel Ferrara's masterpiece: Harvey Keitel as a corrupt cop so deep in moral quicksand he's stopped being a person. No distance, no irony, completely committed to degradation. It's what Impulse's premise could become if taken to its logical end.

But It's genuinely hard to watch—sexual violence, addiction, corruption presented without flinching or redemption. Not edgy, just truthful in ways that hurt.
