Stowaway ★★★½

There's a well-staged ethical conundrum here—the "who would you save in a lifeboat?" question, but in space. The slow-burn tension is riveting, and there's a thrilling space-walk sequence in the final act that stands alongside some of the best in the genre.

But don't expect this movie to be built around set pieces. It's a drama about hard questions and costly decisions. That could be really interesting, especially with this cast, but it's here that Stowaway stumbles. The script sets the problem up well, but the resolution is completely unsatisfying. The whimpering ending undermines an otherwise impressively directed and thoughtfully constructed story.
