Netflix’s IO is an interesting take on post-apocalyptic survival films. Instead of dwelling on a given threat or offering broad strokes that are reflective of societal ills, it presents a more intimate story, one centered on the importance of human relationships. It isn’t always successful. The subdued pace and muted thematic elements that allowed for such nuance also reduced the film’s impact. IO never becomes boring (although there are patches that run the risk of dullness), but it’s also not as noteworthy as it could have been either.
Directed by Jonathan Helpert, IO details the exploits of scientist Sam Walden (Margaret Qualley) after a cataclysmic event sends most of Earth’s inhabitants into space. This mass exodus happens in waves, with some people leaving sooner than others. Sam opts out completely; she’s determined to find a way to save the dying planet. Time isn’t on her side though. With the final shuttle’s departure rapidly approaching, she only has a few days to make a meaningful scientific discovery or face the possibility of being left behind.
