10 Best Monster Horror Movies Of The 2020s (So Far)

10. Significant Other (2022)

Similar in subject matter and scope to Leigh Janiak's Honeymoon, Dan Berk and Robert Olsen's Significant Other nonetheless stands apart, thanks to its deft narrative turns and another dependable horror performance from alt scream queen Maika Monroe. 

Monroe and Jake Lacy star as Ruth and Harry, a couple who are off on their jollies, hoping to enjoy a hiking weekend out in the vast woodlands of America’s Pacific Northwest. But, unbeknownst to them, a red meteor has recently crashed, and its inhabitant, who has caused biological havoc to the flora and fauna, is on the warpath, hoping to come between the kind-of-happy couple. 

Significant Other turns on a rift of awkwardness and suspicion between the couple and the viewer that uses a failed marriage proposal and an off-screen secret to mask its mid-film twist - one that's genuinely unexpected and wholeheartedly justifies itself. But the film really comes into its own when the shape-shifting monster from another planet emerges proper, managing a comic tone that balances out the bleakness, elevating what begins as a slow-moving and rather depressive couple horror to a different breed of monster movie.

The ending might not be for everyone - and, for many of us, feels like it invites a sequel - but the legwork leading up to it is admirable.
