Lovecraftian horror is a tricky genre to nail down. The creeping sense of dread, of being locked in the throes of insanity, has to have some basis in your own imagination -- giving it form or name often softens the scares. The Infectious Madness of Doctor Dekker, which hit Steam last week, is a slow burn. It's not without its share of bumps, but for a subset of FMV enthusiasts like myself, it's perfect B-movie schlock with a hint of Cthulhu.
