John Carpenter was on one hell of a roll back in the 80's! THE THING, CHRISTINE, BIG TROUBLE IN LITTLE CHINA! Holy shit. And then he made PRINCE OF DARKNESS which I think is one of the more underrated horror films of the 80's. It's not your standard slasher flick, which of course I love, he'd already proved himself in that realm with HALLOWEEN and the script for HALLOWEEN II. PRINCE OF DARKNESS was, to me as a little girl, an extremely creepy story about a group of scientists suddenly confronted with the fact that Satan is real. Not in a bullshit Christianity way, but in a much older way and even worse: Satan is just the offspring of a n even more powerful "Anti-God" creature that's been locked away for a really long time and this cylinder full of green liquid in the basement of a derelict church is the key to releasing it! Yikes!
Gorehounds jonesing for a demon splatterfest will be disappointed, but if you're in the mood for a nice 80's demonic creepfest then you're in luck. POD might not have much blood, but it has an awesome suppressive atmosphere about it that stays with you even after the movie is over. There's just something about the idea of being trapped in a building by a creature that actually thrives off of your disbeliefs and can control lower lifeforms like insects and Alice Cooper-impersonating hobos that I found to be especially creepy.
Highly recommended just for Jameson Parker's mustache alone.
