Whether or not you'll actually care about what The Brown Bunny has to offer depends on your indie-weirdness tolerance level. But here's what I "got" from the flick:
Our main character is called "Bud," and throughout his travels he comes across women named Lilly, Rose, Violet, and Daisy. OK, so we have the flower symbolism down cold, got it. Gallo plays Bud as a completely disassociated and frequently fragile outsider, as if he's been hurt in the past and desperately wants to avoid any more emotional entanglements. So he drives and he drives and he drives some more, occasionally bumping into women he likes and/or covets -- but then he drives away again.
At the end of Bud's journey is a former girlfriend with a few shocking surprises. And no, I'm not only referring to the now-infamous blow-job sequence (as performed by the rather, ahem, talented Chloe Sevigny) that caps the movie off with a mildly sexy bout of melancholy weirdness. But if you've made it all the way to the end of Gallo's highway wanderings, at least you'll get some sort of clarification as to what all the driving's about.
I'm not necessarily saying that the "end reveal" makes the movie a brilliant piece of cinema, but for all its rather boring moments, The Brown Bunny still delivers an epilogue that pulls the journey together in rather sobering fashion.
So it's pretty damn dull, intermittently quite intriguing, shockingly sexual at one point, and strangely touching at the very last minute ... which means it's a whole lot like TONS of movies you'll find at the world's film festivals.
Some people adore this odd little experiment; others see an overwhelmingly indulgent piece of junk.
I'm somewhere right in the middle.
