***Undeservedly obscure atmospheric coastal horror*** Two couples in their 30s take a vacation to a secluded isle off the coast when a storm hits and people mysteriously start dying one-by-one. Kay, a troubled artist (Sarah Kendall), says she sees everything in her nightmares before it happens. I suppose “The Slayer” (1982), aka "Nightmare Island," could be classified as a slasher flick, but it’s more accurately a mystery-horror with haunting remote island ambiance, sort of like “The Shuttered Room” (1967), but mixed with elements of moody coastal horror, such as “The Fog” (1980). “I Still Know What You Did Last Summer” (1998) took the stormy island setting to forge a more conventional slasher. The filmmaking is top-notch for the time period, including the superb score. Carol Kottenbrook as Brooke is a highlight, lookin’ good in tight jeans. Kendall shows her acting chops as the haunted protagonist. Meanwhile the titular character is diabolically hideous, but you barely get to see him. Yet there’s a twist and, even then, the movie’s an enigma wrapped in a riddle. The film runs 1 hour, 29 minutes, and was shot on Tybee Island, Georgia, and nearby Savannah. GRADE: B
