Boasting a committed (ho-ho) performance from Claire Foy, my favourite of hers after not quite connecting with her turns in Breathe or First Man, Unsane does a functional if unspectacular job within its asylum-horror sub-genre. Indeed, some of the most frightening details come from the specifics of how Sawyer Valentini - memorably named - ends up in her predicament, and the unspoken implication that this could be happening to many more people as we speak. Confounding at least my expectations by maintaining a solid grip on reality that similar pictures often struggle to resist - this is reinforced by the cinematography. Shot almost entirely on presumably specially lensed and souped up Iphone 7s, you'd be hard pressed to tell versus standard digital photography, giving a utilitarian beauty. Between Soderbergh's work here and Sean Baker's Tangerine, it gives a tantalising sense that any of us could pick up our phones and make a movie - though we just wouldn't have their experience, eye or creativity. Or maybe I should speak for myself. One final note, Joshua Leonard, admirably creepy, Amy Irving, nicely maternal, and Juno Temple - 100% irritating despite a sterling track record with me (Killer Joe, Kaboom as examples) to this point.
