astrid rose’s review published on Letterboxd:
not sure what i expected but this is somewhere south of diet under the skin. garland forces an ultra-conventional narrative onto a spectral, slight book and ends up with ... well, a movie that has the same issues as his SUNSHINE and EX MACHINA. it's milling about in the company of greater work, gesturing in the direction of big ideas and interesting formal decisions but not really trying to measure up—trying would mean risking failure.
moments of inspiration pop throughout, but the lopsided structure (flashbacks!?) necessitates a slasher-esque pace until there are no more bodies to drop and we move on to the ostensibly Heady portion of the picture.
enjoyable enough before the climactic jungian ballet, but don't expect to leave with much.
