Battle Beyond the Stars (1980)
Hadn't seen this one since I was a kid. Not horrible, but not great considering some of the people involved (Roger Corman, John Sayles). And, yes, the spaceship looks like it has boobs.
The Decline of Western Civilization Part II: The Metal Years (1988)
Honestly, I liked this a lot more than part I. Not only was Penelope Spheeris simply a better filmmaker at this point in her career, but the subjects of this movie were far more interesting to listen to than in the first film. I think the key is that all those hair metal guys
knew they were acting like dumbasses, unlike the punks in the first film.
