Anna Kendrick and Toni Collette star in a heady space drama from Arctic writer-director Joe Penna. When a crew of three discover a fourth person on their two-year mission to Mars, they’re confronted with an ethical question of what to do with a limited oxygen supply. There’s plenty of snazzy outer space action and effects, but plot holes and contrivances keep it from ever really achieving liftoff.
3.5/5 stars
