Tasha Robinson’s review published on Letterboxd:
In some ways, typical 80s low-budget horror: Tons of shoe-leather footage of people walking or running to fill time, cheap sets, cheap effects (the prosthetic work is terrifying, the animated effects — by Ralph Bakshi Productions! — are of-their-time cheesy), indifferent acting, what-the-hell plot developments, like the fact that all the women in the film are all over the protagonist, except his harpy ex-wife, who's basically a monster in sorta-human form. On the other hand, for such a laughable production, this is creepy as hell. Great villain, wildly ambitious plot, typically unsettling John Carpenter minimal-synth score, some really weird effects. The story is one of the most creative ideas I've seen in a horror movie — this can't be easily categorized as a slasher film or serial-killer movie or creature feature. Cheesy, but deeply enjoyable.
