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.

Just for Movie Freaks

The ending of Stowaway was very abrupt and did not fit with the rest of the story. It needed an extra 10-15 minutes to show what happens after that moment, and what effect it has on the crew. Instead, the credits instantly roll. Very frustrating.

Rated: 2.5/5

Film Speak

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

But Why Tho? A Geek Community

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.

Rated: 8/10

Good movie up until the ending. A few unanswered questions.

Great story and fantastic acting. Would have loved more time to build some depth a purpose for each character making all of the ending decisions more meaningful but at the end the overall movie was an entertaining and heartfelt watch.

The premise is good, but my God is it frustrating to watch for more than one reason... It's a good background movie, but don't plan a movie night with popcorn around it

PAULO SERGIO CARVALHAES e S

Great movie! It's a tribute to self-sacrifice so often seen in other movies but still rarely present in sci-fi space dramas. What called my attention the most, as a 79 year old movie fan, is that it scares me - positively, I mean- when you compare today's space movies to those produced back in the past century, like in 2001 A Space Odyssey. A super-duper production back then is just a great movie nowadays. Loved Stowayay!

I had high hopes for this film, good casting but the whole story never really developed...no spare parts on board? Nothing nearby they could utilise in a way Sandra Bullock did in Gravity? Metal oxygen cylinder been through solar storm brought back onboard? Radiation?? And so on...
