The women in this collection of animated short stories are very fond of taking off their clothes and/or hopping into bed with men they just met. Not a criticism, just an observation. When you add graphic violence, elements of sci-fi and fantasy, and relatively crude animation to the busty nymphos, you have a slapdash, strangely affecting film that is both irritating and fascinating.
As has been mentioned in several comments, the quality of the stories vary from dull to captivating. The taxi driver tale and the story about the young geek who becomes a muscular hulk are weird and fun to watch; others, like the final story about an avenging beauty clad in a skimpy system of straps, are tedious and revel too much in their unique brand of kinkiness. However, the story about the fighter plane which becomes infested with the living dead is an underappreciated gem.
The writing is average and the animation is pedestrian when compared with some of today's animated classics ("The Iron Giant," "Tarzan"), but "Heavy Metal" is an amusing enough exercise in rock and roll cartooning. (The selection of music is hit-and-miss as well, and the exclusion of Ted Nugent is inexcusable.) If you rent this not expecting much, you might be pleasantly surprised.
