It’s been 16 years since Jake Kasdan’s “Walk Hard: The Dewey Cox Story” read the musical biopic to absolute filth, and while there have been a few good movies in the genre that followed, it’s amazing that more filmmakers didn’t actively attempt to repudiate “Walk Hard’s” claims. All the tired clichés and the hackneyed melodrama Kasdan’s film upended are still the industry standard. When, oh when, is a film finally going to accept the challenge and show that there’s still something new to be done with the genre?
The answer, dear readers, is right now. “Kneecap,” a new film about an Irish hip-hop trio that raps in the Irish language and premiered at Sundance on Thursday, is a snort of ketamine in a very uptight world.
