Andrew Wyatt’s review published on Letterboxd :
An existential techno-horror meltdown for the current, performative era of the digital age, Daniel Goldhaber’s 'Cam' is centered on full-time camgirl Alice, a.k.a. “Lola” (Madeline Brewer), who live-streams her NC-17 frolicking and edgelord faux suicides to chatrooms of enthusiastic, anonymous viewers. As it chronicles the banal details of Alice’s routine with a stylized, candy-colored eye, 'Cam' initially seems to be setting up a sex worker spin on the “obsessed fan” thriller. In truth, scripter Isa Mazzei – who drew from her own experiences as a camgirl – creates something cleverer and much more unsettling. Abruptly, Alice discovers that she’s been locked out of her account by a doppelgänger who begins climbing in the rankings and siphoning her income. It’s this year’s 'Unfriended: Dark Web' by way of 'Lost Highway' (1997) and 'Enemy' (2013), with a hefty dose of gig economy anxiety. Mazzei and Goldhaber take that heady concoction to some harrowing places, but they ultimately keep the story frustratingly grounded, never fully realizing its nightmarish potential.
