Critics Consensus

Pacing problems prevent Stowaway from fully engaging, but it's distinguished by its thoughtful, well-acted approach to a story built on an excruciating moral dilemma.

Audience Says

Although it's well-acted and beautifully filmed, this cleverly conceived sci-fi drama is undone by its predictable, drawn-out story and a frustrating ending.

Such a tightly written and engaging character piece that it overcomes an unconvincing premise.

Stowaway, it turns out, is just as intricate and immersive.

Just about every confusing plot point is overcome by a powerful human moment.

C-

Despite a great cast and blissful imagery, the impact of ‘Stowaway’ is dulled by an uninspired story.

8/10

Stowaway is not complex, nor is it trying to be, but if you’re looking for a quick distraction that’ll leave your palms sweaty and your heart racing, then this is well worth your time.

{Stowaway} completely mishandles any chance of a morality play by playing it too safe. It’s such a flat experience that it made me ponder whether the world is round after all.

Semi-interesting premise. Good actors. Terrible script. And the ending seems like the writers just gave up.

Absolutely terrible film, actors are well known but such a boring storyline with an awful ending. Would definitely not recommend watching. Waste of hours of my life!

The premise about the ethical dilemma of survival in space is excellent, but the film sabotages itself with an incredibly slow pace and plot holes that are hard to ignore.

This 2021 film is a product of its time - woke garbage featuring the popular trope of a virtuous white woman who suspends all logic and reasoning for the opportunity to be a savior to someone undeserving. The plot and science is so bad, it’s unworthy of being called science fiction.

A good, exciting sci-fi film. Original, tense, entertaining. This film wasn't ground-breaking but was honestly pretty good and interesting the whole way.
