"Variety" gave the film a negative review, calling it a "wildly uneven horror film," noting that "More care in scripting and fewer cheap yocks could have resulted in a viable new paranoid horror myth." Vincent Canby also criticized the script in his review for "The New York Times", stating, "The screenplay is stitched together from variations on cliches used by or about the medical community." "The Washington Post" noted that "Manny Coto turns to co-writer Graeme Whifler time and again for punchlines in a desperate attempt to revive a script that begins in critical condition and ends up DOA."
