Jim Muro’s crazed 1987 horror comedy is a unique snapshot of its times, when bad-taste humor intersected with Reagan-era loathing of the poor. The owner of a skid-row liquor store uncovers an ancient case of hooch called Viper and sells it for a buck a bottle to the bums who congregate around a nearby junkyard; when they drink it, their flesh melts into puddles of multicolored (but mostly blue) goo. The movie is a smorgasbord of smut, gross-out gags, and grisly special effects, with politically incorrect digs at blacks, women, the disabled, Vietnam vets, and, of course, the destitute. There’s something to offend everyone, though the perversity can be inspired: puckish oboe music accompanies a scene of a woman being crushed by her horny, 300-pound boss, and the score turns to jolly barrelhouse rock ‘n’ roll as a bum chases around the junkyard after his severed penis, which is being tossed back and forth by his guffawing buddies. This may make you laugh, or it may make you sick (or both). 101 min.
