What the Heck is this flick? It's not really a comedy or horror movie, it's not really sci-fi, and I'm pretty sure it's not a drama. Mystery, thriller, Western- there's not a genre section at Blockbuster that can tame this wily beast of a movie!
Here's what it is, as far as I can tell: A mysterious pharmaceutical company, run by one naked woman and a bunch of muscle-bound squeeky voiced guys, is secretly testing it's new drug on the inhabitants of a small housing complex somewhere in New Zealand. They also front a health spa where their unwitting test subjects come to have their urine sampled. The drug is, of course, malfunctioning, and all the folks who take it eventually mutate in various ways (not many of them actually melt, as the title implies. Most explode).
In one subplot, two lustful teens are off to donate sperm but get lost and end up with a bizarre backwoods family with big welts on their faces. The teens hang out with the inbred yokels for a while, watching them eat kangaroo glands and riding in the truck from "Even Dwarves Started Small". Unfortunately, one of the guys puts the moves on the huge, revolting sister in the family and gets a stake in the loins.
Other highlights include killer placentas, exploding genitals, huge swelling tongues, and tons of other gore (from the people who handled the effects in "Dead Alive"). This movie is a sloppy good time, for no one escapes the wrath of... BODY MELT! Recommended!
