Never overstays its welcome and builds up to its shocks by having us get to know Harry and Ruth before it turns the tables on the audience

If for some reason you haven’t pulled the trigger on Shudder and want to get more out of a Paramount+ subscription, this is better than just staring at a blank wall.

The film’s modest facade proves a smoke screen for a rich and eventful ride; one plot development in particular hits with such surprise that it catches the audience far more unawares than the characters.

A surprising science fiction thriller that serves original twists you won’t see coming.
