"Buckley and Kinnear bring a terrifyingly trippy battle of the sexes to Garland’s throat-grabbing folk-horror freakout. Outstanding."
★★★★★  Kate Stables, Total Film

"Before the film reaches its perplexing final act, Garland has crafted an effective chiller, albeit one with a painfully unsubtle feminist subtext."
★★★★★  Andy Lea, Daily Express

"Alex Garland once again shows an unmatched ability to conjure a beautifully uneasy atmosphere, the sense of which lingers on past the closing credits "
