A politically problematic, overwritten and at times fairly dumb but still partially suspenseful and atmospheric occult horror of faith and science.
Stylistically, this is recognisably a John Carpenter movie, with another group of isolated characters battling for survival, set against a moody synth soundtrack - unfortunately however, it falls flat on pretty much every level. Where the mix of SF and horror worked brilliantly in 'The Thing', here the attempt to merge supernatural horror with scientific theory just feels messy, whilst the threat element is too nebulous ( we have an eerie glowing container, murderous tramps, zombies who shoot water from their mouths, people who turn into bugs, and a demon from a mirror dimension) to act as a strong hook. Worst of all, the characters are all flat and uninteresting, so it's hard to care when they die anyway - even Donald Pleasance can't save this script.
