Satan is discovered in the basement of a disused church, in the form of a
large vial of bubbling green liquid, and infects whoever gets too
close. A really awful mix of religious mumbo-jumbo and zombie action,
this long outstays its meagre welcome, with some very tedious
exposition, dull performances and inert suspense. Shockingly bad for
John Carpenter, even compared with the very ropiest of his earlier
movies, and a real indication of decline. Even Donald Pleasence is
defeated by the stilted literariness of the dialogue, and your
wakefulness certainly will be.
