It’s difficult to discuss what a movie like Vulcanizadora is about without ruining it for everyone else. So let’s not spoil things! I’ll keep this brief.

Marty (Joshua Burge, 2015’s The Revenant) is a perennial sad sack. His friend, Derek, is a motormouth with a chunk of hair that looks like it leapt from his cranium, clung to his chin and died. The salt to Marty’s vinegar, Derek is played by the film’s writer, director and editor, Joel Potrykus.

Armed with cheap fireworks and a canteen of Jägermeister, they’re taking their first steps on a camping trip like no other, deep into a Michigan forest. Thus begins a slackerpalooza of junk food, spank mags, candle lighters, petty arguments and the stark reality they were ill-prepared for adulthood, so they’ve essentially stayed children.

Their mission? Yes, they actually have one, but this secret sequel to Potrykus’ Buzzard is not about to spoon-feed you those details until it’s damn well ready. And once it is, you won’t be.

Vulcanizadora (Spanish for “tire repair shop,” which figures into the stealth plot) arrives more twisted than a box of garlic knots from the corner store freezer. A two-hander for a majority of its running time, this M-80 of an indie revels in comedy as black as it is bleak. I can’t help but admire what Potrykus achieves in this daring high-wire act. Love it or loathe it, no one is likely to shake its memory. —Rod Lott
