Daniel Roher's directorial debut "Tuner" follows a piano tuner who pivots to safecracking, anchored by a central romance that carries the film through its familiar beats. Havana Rose Liu delivers a revelatory performance that forms the emotional core of the film, bringing depth to material that often treads predictable narrative ground. Leo Woodall, miscast in his supporting role, struggles to find purchase in a character that the script hasn't quite figured out.

Roher's transition from documentarian to narrative filmmaking shows promise but also restraint. The premise itself contains inherent charm: a protagonist whose precision-honed ear and meticulous touch translate naturally from tuning instrument strings to manipulating vault mechanisms. That thematic throughline suggests a filmmaker aware of craft and detail. Yet the story unfolds along well-worn paths, hitting expected plot points without the lateral thinking that might have elevated standard romance-heist territory.

The film's pleasures are real but modest. Liu's performance transcends the script's limitations, suggesting an actor capable of commanding more substantial material. She brings authenticity to moments of vulnerability and credibility to sequences where a character might otherwise feel like a convenient plot device. The chemistry between leads works despite Woodall's miscalibration, though the film never quite justifies why this particular pairing matters beyond surface attraction.

What "Tuner" needed was willingness to zig when audiences expected it to zag. The heist mechanics lack urgency. The romance follows contours viewers recognize from countless predecessors. The supporting characters register as functional rather than felt. Roher demonstrates technical competence and visual intelligence, but narrative boldness remains absent. He captures moments of genuine pleasure, particularly in sequences where the film explores its protagonist's relationship with sound and precision, but these islands of interest struggle to cohere into something that resonates beyond the theater.

"Tuner" works as a vehicle for Liu's talents and a respectable first narrative feature for Roher. It doesn't work as something that reshuffles the deck or takes real risks.
