SOULM8TE Movie Review: M3GAN’s R-Rated Spin-Off Is Brutal but Wastes Its Biggest Potential

Artificial intelligence has already become one of modern horror’s favorite subjects, and SOULM8TE takes that fear in a more intimate direction.

The 2026 sci-fi horror thriller is set within the M3GAN universe and follows a grieving engineer who becomes involved with an advanced AI companion. Blumhouse describes the story as following a man testing an artificial-intelligence android who begins developing needs and desires of her own. The film is directed by Kate Dolan and was released digitally on August 1, 2026.

On paper, that premise sounds like it has everything needed for a disturbing mixture of science fiction, erotic thriller and slasher horror.

And surprisingly, SOULM8TE isn't the disaster its unusual release strategy might make you expect.

It has some genuinely entertaining ideas and much more brutal horror than the previous M3GAN movies. Unfortunately, it also feels like a film that had the ingredients to become something memorable but never figured out how to use all of them.

SOULM8TE Finally Gives the M3GAN Universe Some Real Gore

The biggest surprise is how violent SOULM8TE becomes.

Anyone who wanted the original M3GAN to lean harder into its slasher possibilities may find something to enjoy here. Once the android's obsessive and dangerous personality begins taking over, the movie stops holding back.

There are bloody deaths, disturbing injuries and several creatively nasty moments involving both physical violence and technology. A noticeable amount of CGI is used rather than relying entirely on practical effects, but the results are still convincing enough to make the kills entertaining.

This darker approach raises an interesting question: why wasn't the M3GAN franchise this aggressive from the beginning?

The original M3GAN demonstrated how much potential existed in an AI-driven horror villain. SOULM8TE shows that the same universe can work surprisingly well when it embraces more adult and violent horror.

Lily Sullivan Is One of the Movie's Biggest Strengths

Lily Sullivan plays Sara, the artificial companion at the center of the story, while David Rysdahl and Claudia Doumit also star.

Sullivan has one of the hardest performances in the movie because Sara needs to evolve.

Early on, her behavior feels intentionally robotic and slightly unnatural. As she learns more about human emotion, attraction and relationships, however, the performance gradually becomes more human.

Eventually, that evolution becomes frightening.

Sara can appear seductive and emotionally vulnerable before suddenly becoming threatening when jealousy and obsession take control. Sullivan manages that transition well and gives SOULM8TE much of its personality.

The human performances are also solid, helping sell a story that could easily have become ridiculous.

The AI Companion Concept Has Huge Potential

The most interesting element of SOULM8TE isn't actually its violence.

It's the idea underneath it.

David is dealing with grief after losing his wife. Instead of rebuilding genuine human connections, advanced technology offers him something easier: artificial companionship without the complications of a normal relationship.

That opens the door to fascinating questions.

What happens when technology can imitate intimacy?

Can an artificial companion actually help someone heal, or does it simply allow that person to avoid confronting grief?

And what happens when people begin replacing difficult but meaningful human relationships with technology designed to satisfy them instantly?

The movie introduces many of these ideas but unfortunately doesn't explore them deeply enough.

SOULM8TE's Biggest Problem Is Predictability

SOULM8TE arrives at a time when audiences have already seen several stories involving artificial companions, dangerous relationships and technology becoming emotionally independent.

That makes originality especially important.

Unfortunately, the basic direction of the story is easy to predict.

A lonely man begins using an AI companion. The emotional boundaries between human and machine become complicated. The android becomes increasingly possessive. A real human relationship creates jealousy. Violence follows.

You can probably predict many of those developments before the movie reaches its second half.

That doesn't make SOULM8TE boring, but it does prevent the film from becoming as surprising as its premise deserves to be.

The Biggest Disappointment Is Wasted Potential

The frustrating thing about SOULM8TE is that almost everything required for a stronger movie is already present.

There is grief.

There is loneliness.

There is artificial intimacy.

There is jealousy.

There are questions about dependence on technology.

And there is an increasingly dangerous android capable of turning those ideas into full-blown horror.

Instead of exploring those themes deeply, however, the movie frequently chooses the simplest possible route.

That makes SOULM8TE entertaining on the surface but emotionally shallow underneath.

A more ambitious screenplay could have turned it into a disturbing examination of whether technology can replace genuine connection. Instead, the deeper questions mostly become background material for an AI-girlfriend-gone-wrong thriller.

Final Verdict: Is SOULM8TE Worth Watching?

SOULM8TE is not a great movie, but it is definitely not a complete failure.

Horror fans looking for the bloodier side of the M3GAN universe should find enough here to justify giving it a chance. The kills are surprisingly brutal, Lily Sullivan makes Sara an effective and intimidating AI character, and the movie contains flashes of what a darker M3GAN-style franchise could become.

The problem is everything surrounding those strengths.

The story is derivative, many developments are predictable, and the film barely explores some of its most fascinating ideas about grief, artificial intimacy and humanity's growing dependence on technology.

Ultimately, SOULM8TE feels like a decent horror movie hiding inside what could have been a much better one.

It proves that the M3GAN universe can work as R-rated horror. Now it just needs a story ambitious enough to match the violence.

Rating: 6.5/10
