If you haven't seen Buckaroo Banzai, I recommend it. It's one of the great "cult" movies.
Not too cult, though, since here's the NY Times review.
At its best, which it frequently is, it's a lunatic ball, an extremely genial, witty example of what is becoming a movie genre all its own. That is, the science-fiction farce . . .
Absolutely nothing in ''Buckaroo Banzai'' is quite clear, nor is it supposed to be, though most of it is very funny, beginning with the opening sequence.
