Stowaway ★★★½

Sympathetic characters stuck in an unsympathetic space! And in case you are into made-up rankings, the cosmos just squeak past the ocean for the "scariest place to be when things go wrong" award.

The performances are solid, and each member of the small cast feels like a real human being making rational decisions in a time of crisis. For that, Stowaway earns some positive marks. It boasts some great production design--this definitely felt like the not-too-distant future of space travel. It is a drama first-to-last, with only one really thrilling segment. No problem here. The lack of an alien threat, action sequences, or even a clear antagonist helps set this apart. It's a simple story, told surprisingly well.
