The Polka King (2017)

The Polka King is the kind of “only-in-America” true-story comedy that wins you over with sheer oddball momentum and a surprisingly sunny spirit. Jack Black turns Jan Lewan into a whirlwind of charm and hustle—part musical ringleader, part delusional dreamer—and the movie wisely lets his performance carry the laughs and the warmth. The vibe is buoyant and weirdly wholesome even as it tiptoes into darker, more absurd territory, making it feel less like a cynical takedown and more like a backstage pass to a bizarre little corner of ambition. If you need tight storytelling and razor-sharp satire, it may feel a bit loose, but if you’re on the fence, this is an easy watch that’s funny, heartfelt, and improbably optimistic.

The Polka King is clearly trying to be a quirky true-story comedy about a lovable oddball whose ambition curdles into something darker, and Jack Black commits hard to the big, goofy energy. The problem is the movie can’t quite decide if it wants to be a sharp con-man tale or a light farce, so the pacing drags and the laughs arrive in uneven bursts. The script skims the surface of what makes Jan’s choices fascinating, which can make the whole thing feel sloppy and a bit disposable rather than revealing. If you’re mainly here for Black doing a strange accent and a few amusing moments, you might have a decent time; if you want tight storytelling or real depth, this likely isn’t for you.
