There's few things in cinema quite as satisfying as a good creature feature. When done well, it gives particularly confident, creative filmmakers a chance to shine and introduce all manner of unique horrors on the audience. Cuckoo, the sophomore effort of Tilman Singer, is an excellent example of a good creature feature. While it hardly attempts to reinvent the wheel, one can see the blending of influences to create something unique, an eerie and disturbingly intriguing mystery box that unravels piece by piece, but never kills it's mystique by overexplaining itself. It's also a lot of fun! Hunter Schafer is endlessly battered on a quest for answers, the monsters are cool, and the GOAT Dan Stevens plays an endlessly slimy quasi-Nazi. What's not to love?
Cuckoo's central idea is all about the idea of the "other", the outsider trapped in a situation they simply don't belong in. On the one hand, this represents Gretchen (Hunter Schafer), a queer teenager reeling from the death of her mother and forced to live in a remote German resort with her father's family, but it speaks just as much for the monsters of the film: a brood parasite-esque offshoot of humans that place their females amongst humans to raise until they come of age. Much of Cuckoo is as much about Gretchen's struggle in this environment as it her uncovering the central mystery of the resort. She is isolated, bitter, and looking desperately for a connection of any kind to anchor her through the terrifying circumstances in display, be it through a (potentially ill-advised) relationship with aloof French musician Ed (Astrid Berges-Frisbey) or her tenuous alliance with undercover cop Henry (Jan Bluthardt). This fumbling for connection in the face of deeply painful loss makes up the true heart of the film, anchoring it for very real, very earned emotional beats as the film heads into it's climax.
Schafer, unsurprisingly, is very good at selling this struggle and desperation. She mixes both the idea of the scream queen with that of a very real, grieving person with aplomb, her expressive eyes and agonized physicality as she finds herself beaten and battered again and again. You don't just want her to succeed, you feel every single hit for yourself. Opposite her is the always delightful Dan Stevens as Herr Konig, resort owner/mad scientist, who contrasts Gretchen's scrappy, aloof reality with a restrained sense of menace and cruelty. He's quiet, polite, but dripping with condescension, carrying himself as someone who feels in power at all times. It's all in how he carries himself, imposing himself in the space of others while remaining upbeat, just as likely to smile while describing a hotel clerk job as he is while witnessing one of the creatures attempt to force itself on Gretchen. It's affable cruelty, an uncaring face on a violence that brims with both social and psychosexual commentary. Every scene between the two feels increasingly like a game of cat and mouse, Konig hoping to crush Gretchen under his boot without a second thought while Gretchen to survive.
And like I mentioned prior, Cuckoo, despite it's grim subject matter, never presents itself as a downer. It's a lot of creepy fun, full of spooks and tense moments, slowly uncovering the central mystery of the resort, and Singer has a really excellent visual eye, framing the gorgeous locale of the German countryside as something deeply menacing and isolated while playing with the shadows to create an endless feeling of paranoia. In one particularly fun sequence, Gretchen's bike ride home from work is interrupted by an attack by the creature, it's shadow growing closer and closer behind her while she rides along, completely unaware. The creatures themselves benefit from a similarly impeccable presentation, their largely humanoid features but animalistic, snarling body language pushing them into the uncanny valley. Their screeches, used as form of hypnosis and communication, are piercing and ethereal, and the depiction of the hypnosis, a time loop the victims recognize but are agonizingly unable to escape from, is a unique presentation that plays well into the ongoing mystery, while the death of the "mother" is quietly sad, a gurgling, undignified end of a creature that simply didn't know any better.
It's the quiet moments of emotion like that which make Cuckoo such a strong film. There's an undeniable, quiet heart to the film's quieter moments, be it Gretchen listening to half-sister Alma's (Mila Lieu) message to her deceased mom or her outpouring of grief with the similarly mourning Henry, and the film's climax is ultimately settled not with an outburst of violence, but of love and ingenuity, as Gretchen finally accepts Alma as family and works with her to escape. It's a cathartic, unexpectedly sweet finish, and it makes the ending feel like the exhale of a breath you didn't know you were holding. Tense and scary without being grim and overbearing, this tonal balance makes Cuckoo one of the strongest of this year's considerable bounty of horror efforts.
