"Woe be unto him who opens one of the seven gateways to Hell, because through that gateway, evil will invade the world." Really, Eibon? I thought opening a gateway to hell gave everyone rainbows and ice cream and unicorns </sarcasm>
The Beyond (1981): Wonderfully atmospheric and surreal and creepy. The gorier scenes feature some very impressive special effects for the era as well, and even the music holds up better than I would have expected. The acting isn't great, but that isn't really the point. Also, Dr. John McCabe is the worst shot ever to face off against slowly shambling zombies at barely more than arm's length.
