Warp’s review published on Letterboxd:
Mediocore sequel that is inferior in all aspects to the great Dèmoni. There is little or nothing to do, both in terms of film technology and entertainment value. It takes half an hour for all to break loose but even then it all remains sleep-inducing. The action scenes look lousy and the amount of rancidity was also very disappointing. The only scene worth mentioning is the one in the elevator shaft, but apart from that one scene, it isn’t really bad, but it is unworthy of the names Bava and Argento.
