The real delight of Buckaroo Banzai is its incomprehensibility. Unlike the incomprehensibility of movies like John Boorman’s Zardoz, or even 2001: A Space Odyssey, which tend to alienates audiences, the name of the game in Banzai is fun, particularly if you’re into comics, sci-fi, and rock n’ roll (read: ardent readers of this website). It’s always a step ahead of the audience, with another trick up its sleeve, or some dangling plot thread that promises more. There’s enough backstory here to provide the plot for several lesser films.
